Instructions for Use of Cable Fault Tester
Instructions for Use of Cable Fault Tester
When using the cable fault tester, we should first look at some simple waveform diagrams to analyze different cable faults, and then find out the fault points through the corresponding methods. The following is our simple analysis and description. 1. Test the low resistance grounding, short circuit and open circuit faults of the cable with the low voltage pulse method. A. no other auxiliary equipment is needed at this time. A clip wire is directly connected to the input and output interface of the cable fault location host. Clamp the red clamp of the clamp wire on the faulty phase core wire of the faulty cable, and the Black clamp on the sheath ground wire of the cable. B. Start the power switch of the instrument, the screen saver picture will appear on the screen, and click to enter the interface automatically. At this time, the default state of the instrument is "low voltage pulse method". The use method shall be selected according to the type and length of the tested cable on site and the fault nature preliminarily judged. When it is set to "low voltage pulse method", wave velocity measurement can also be carried out on this interface, and historical files can be opened to view previous test results. C. After setting the equipment parameters, click the "sampling" button, and the instrument will automatically send out test pulses. This interface will display the (open circuit) full-length waveform of the cable (as shown in Figure 5) or the low resistance grounding (short circuit) fault waveform (as shown in Figure 6). If the waveform is not good, the operator shall adjust the "median" and "amplitude" and observe the collected echo until the operator thinks that the amplitude and position of the echo are suitable for analysis and positioning. Basic information such as instrument parameter setting is also displayed at the bottom of the screen. During operation, pay attention to the operation status at the bottom of the screen. D. Waveform positioning reading distance. It is easy to judge the distance of low-voltage pulse, as long as the cursor is positioned to the starting point of transmitted and reflected waves respectively. E. When "saving", the test results need to be retained or reserved for comparison. The "saving" function in the instrument should be used to save the measured waveform in the instrument database. If the tester thinks it is necessary to save the test results, he can click "save" and operate according to the prompt in the submenu. 2. The high resistance leakage fault (including high resistance flashover fault) of the cable is tested by the impact high voltage flashover method. The instrument can test the high resistance leakage fault of the cable by the impact high voltage flashover method. Impulse high voltage flashover method is a popular traditional detection method in China. Many users are used to this method. The external circuit is relatively simple, but the waveform analysis is more difficult. Only on the basis of a large number of tests and some experience can we master it skillfully, but it is still an effective test method. Connect the current sampler attached to the instrument with the host with the signal wire and place it next to the grounding wire between the cable and the high-voltage equipment. As long as the output voltage of the impulse high voltage generator is high enough, the fault point will be broken down under the impulse of this impulse high voltage, and the radio wave reflection will be generated in the cable. The current sampler transmits the induced reflected wave obtained from the current signal on the ground wire through magnetic coupling to the cable fault location host for a / D sampling and data processing, and displays the collected waveform on the screen for fault distance analysis. After the cable type and sampling frequency are determined, you can click the "sampling" button to wait for sampling. Once the high-voltage generator has impulse high-voltage flashover, the instrument will automatically carry out data acquisition and waveform display. The red waveform at the top of the screen is the waveform after local amplification, and the blue waveform at the bottom is the full picture of the test waveform. When the ideal waveform is collected, the "waveform scaling" and displacement and moving cursor can be operated to calibrate the fault distance. The operation method is consistent with the low-voltage pulse method. 3. Wave velocity measurement cables produced by different manufacturers, although the models are the same, the differences in process and medium formula will lead to the differences in radio wave propagation velocity. If the average wave propagation speed given by the instrument is directly used, it will cause a certain test error. In order to test the fault distance more accurately, it is often necessary to recheck (test) the radio wave propagation speed of the cable.
This Paper Briefly Introduces the Fault Detection Method of High Voltage Cable
This Paper Briefly Introduces the Fault Detection Method of High Voltage Cable
The discovery and fixed-point work of cable faults has always been a big problem in the electrical measurement industry, mainly because most cables are deeply buried underground, the laying distance ranges from a few meters to a few kilometers, and the on-site environment is complex. In addition to the high quality requirements for cable fault test equipment, the comprehensive quality of technicians is also very strict. There are three common types of cable faults: low resistance fault, high resistance short circuit grounding fault and flashover fault. For different types of cable faults, the fault point detection methods are also very different. The following is a brief introduction to the fault detection method of high-voltage cable. There are two kinds of traditional fault detection methods for high voltage cables: bridge method and pulse method. 1、 Electric bridge method is a classical method for ranging power cables. This method is relatively simple, but it needs to know the data such as cable length in advance, and it is only suitable for low resistance and short circuit faults. However, in actual operation, faults are often high resistance and flashover faults. Due to the high fault resistance, the bridge current is very small, so it is difficult for general sensitivity instruments to detect. 2、 Pulse method 1. Pulse current method this method is safe, reliable and simple. The method is to break down the cable fault point with high voltage, collect and record the current traveling wave signal generated by the fault click through with the instrument, and calculate the fault distance according to the round trip time between the current traveling wave signal at the measuring end and the fault point. In this method, the pulse current is coupled with a transformer, and the waveform is simple and safe. This method also includes direct flash method and impulse flash method. Different from the pulse voltage method, which uses resistance and capacitor voltage dividers for voltage sampling, the pulse current method uses linear current couplers placed parallel to the low-voltage geodesic and has no direct electrical connection with the high-voltage circuit. It is particularly safe and convenient for recording instruments and operators. So people usually use this method. 2. Pulse voltage method this method can be used to measure high resistance and flashover faults. Firstly, the cable fault is broken down under the DC or pulse high voltage signal, and then the distance is measured by recording the time required for the discharge pulse to go back and forth between the measuring point and the fault point. An important advantage of pulse voltage method is that it does not have to burn through high resistance and flashover faults. It directly uses the instantaneous pulse signal generated by fault breakdown. The test speed is fast and the measurement process is simplified. 3. For low resistance and open circuit faults, the pulse echo method uses the low-voltage pulse reflection method to measure cable faults. Compared with the above bridge method, it is simple and direct. It only needs to observe the time difference between the reflection and transmission pulses at the fault point to locate the fault. During the test, a low-voltage pulse is injected into the cable. When the pulse propagates to the fault point, it will be reflected, and the pulse is reflected and sent back to the measuring point. The time difference between the transmitted and reflected pulses is recorded by the instrument, and the distance of the fault point can be calculated only by knowing the pulse propagation speed. This method is simple and intuitive. It does not need to know the original data such as cable length. It can also identify the position of cable joint and branch point according to the reflected waveform.
LC Duplex Fiber Connector for High-density Cabling
LC Duplex Fiber Connector for High-density Cabling
Due to its small size, LC connector is the mainstream fiber optic connectors and is widely used in optical communication networks, data networks, and cable television networks. In daily application environment, LC duplex connector used more often because of its cabling space saving. LC duplex fiber optic connector is two simplex LC connectors encased in a common housing. Compared with LC simplex connector, the installation steps are reduced, saving time and money.HYCs LC duplex connector is superior to traditional LC duplex connector, providing an innovative solution for quick unlocking. Compared to the traditional two single connectors, this duplex connector only needs one press to achieve double releasing. As shown in Figure 2,3, the design of this two-core connector has two advantages, one is the longer clip and another is a lower clip. The extended longer latch on top of the connector body makes it easier to disengage from the adapter, even in high-density packaging. If you have the experience of releasing LC duplex connectors in patch panels in high-density cabling, you may know why this is important. Because in the cabling case, thumbs and forefingers are not ideally suited to operate the release lever and pulling the connector. The handle portion of a conventional duplex connector will be slightly higher than the adapter, which will take up more space during the cabling installation. The lower clip design of this LC duplex connector can save more space. In the high-density environment of the data center, the space saved by multiple connectors is combined to have a great advantage.Another important advantage is the ability to reverse polarity. In the optical signal transmission, the optical signal is divided into a receiving end and a transmitting end. The optical fiber link transmitting signal (Tx) at one end of the optical cable must be matched with the corresponding receiver (Rx) at the other end, and the matching is called polarity.Conventional LC fiber jumpers have significant limitations in achieving polarity switching. It is necessary to pay special attention to the direction of polarity transformation to avoid the failure of termination and face the possibility of replacing the jumpers and re-cabling. The ability to switch the polarity of this LC duplex connector makes this operation easier, saving a lot of time and wiring costs by easily switching polarity without any tools.With the rapid application of 5G, how to provide a high-density, low-cost, easy-to-manage, and highly reliable network cabling system for data centers has become an increasingly important requirement. The LC duplex fiber optic connector is a high-reliability, low-cost, high-density cabling solution. Originally published at wordpress. com on April 27, 2019.

Contingency Base Camp Workshop.
Contingency Base Camp Workshop.
In early May 2006, the United States Army Engineer School and the United States Military Academy (USMA) cohosted the 3d annual Contingency Base Camp Workshop in St. Louis, Missouri. The workshop was held during ENFORCE week to emphasize the importance of contingency base camps to the engineer mission. Participants were divided into one of three focus areas for the workshop: the Base Camp Knowledge Management System, Initiative 18, or Infrastructure Assessment. [ILLUSTRATION OMITTED] Base Camp Knowledge Management System The Base Camp Knowledge Management System, designed to be a Web-based knowledge portal for base camp planners and managers, was developed by the USMA using input from previous base camp workshops as a guide for management system requirements and capabilities. The system was developed to address the lack of a secure, fully integrated means of sharing information and transferring knowledge with other members of the base camp management community. The knowledge management system for base camps will provide an expeditious means for planners, designers, operators, and managers of base camps to share their knowledge. It will provide the process to develop and enforce methods for sharing operational information and conversion of data and information to actionable information, as well as eliminating or reducing information stovepipes among operational elements. Initiative 18 Initiative 18--from the Chief of Staff of the Army's task force on stability and reconstruction--establishes and provides base operation capabilities to support the operational Army in a contingency environment and city management expertise to support the host nation. The base camp workshop addressed the base operations support aspect of the initiative, specifically addressing the recommended course of action from the Initiative 18 Working Group that was sponsored by the United States Army Corps of Engineers[R] (USACE). The course of action discussed the establishment of a proponent for contingency base camps. The Army has 303,000 Soldiers deployed to 120 different countries to support the Global War on Terrorism. Department of Defense Directive 3000.05, Military Support for Stability, Security, Transition, and Reconstruction (SSTR) Operations, states that stability operations are a core U.S. military mission that the Department of Defense shall be prepared to conduct and support. Critical in the support of SSTR operations is that deployed contingency operations will require base camps. While doctrine developers often think in terms of deployed forces being at the "tip of the spear," the fact is that the tip of the spear needs to be correctly joined to the shaft. That joining point for Soldiers currently deployed is the base camp, where at the end of the day's fight, they link back into the logistics and support systems that prepare them for the next mission. Currently, the process to address base camp issues is done on an ad hoc basis, depending on the mission, operational area, and scale of operations. Combatant commanders divert their energy and resources to addressing base camp planning, design, and functionality--which are often outside the scope of their mission emphasis and in many cases should have been completed before establishment of the base camp. The present system is a sum of several parts controlled by different organizations, including-- * Research, Development, and Engineering Command (RDECOM) (United States Army Natick Soldier Center) * United States Army Combined Arms Support Command (CASCOM) (Quartermaster) * United States Army Materiel Command (AMC) (Logistics Civil Augmentation Program [LOGCAP]) * USACE (Forward Engineer Support Team [FEST], Environmental Support Team [EnVST], Contingency Real Estate Support Team [CREST]) * Engineer Command (ENCOM) (Facility Engineer Detachment [FED]/Facility Engineer Group [FEG]/Facility Engineer Team [FET]) Without an overarching proponent, coordinating resource challenges can result in insufficient preplanning, design shortcomings, operational issues, and the lack of an established research and development program to seek solutions proactively and quickly as operational gaps are identified. These factors can be compounded by extended operational requirements. Currently there isn't a base camp proponent. The Initiative 18 course of action recommends to the Chief of Staff of the Army that the Engineer School be the proponent for contingency base camps. This would include the formation of an integrated concept development team, with representatives from all organizations that provide support for the individual systems that make up base camps. Workshop participants agreed with the recommended course of action and provided additional recommendations for participation in an integrated capabilities development team (ICDT) to be developed by the proponent. Infrastructure Assessment The infrastructure assessment group discussed several topics. Workshop participants stated that units want a capability to go to a possible base camp site, obtain critical information, and pass this information back to planners. Two equipment kits were discussed in detail: the Handheld Apparatus for Mobile Mapping and Expedited Reporting (HAMMER[TM]) and the Engineering Field Planning, Reconnaissance, Surveying, and Sketching Set (ENFIRE). Both have the capabilities to provide the necessary support to assessment teams. HAMMER HAMMER is a ruggedized, handheld field computer for collecting geospatial data with high-resolution digital instrumentation. The device is a product of a cooperative research and development agreement between the Construction Engineering Research Laboratory and Surveylab, Ltd. The product seamlessly integrates and synchronizes a global positioning system, laser distance meter, digital camera, compass, inclinometer, geographic information system (GIS), and handheld computer. This allows users to quickly capture a rich array of geospatial and attribute data, annotated with images and text, such as capture and review a target position and photo, add attribute data to the feature, review and add photos, and view the new feature on a map. The instrument's database stores and shares data, and the automated GIS-based system facilitates data analysis, interpretation, and reporting. HAMMER will be demonstrated and field-tested this year. ENFIRE ENFIRE is a prototype system focused on enabling Soldiers to conduct reconnaissance on routes, bridges, and minefields by replacing the current surveying sketch kits with digital reconnaissance forms that match currently used hard-copy forms to facilitate data collection. ENFIRE supplies Soldiers with software and hardware tools to gather reconnaissance and reporting information, project management tools, a digital library of field and technical manuals, construction project building-design software, construction site terrain-modeling tools, an inventory management package, and tools to disseminate information to the Army Battle Command System battlefield functional areas. ENFIRE was demonstrated at Fort Leonard Wood, Missouri, in May 2006. Conclusion Overall, it was a very successful base camp workshop with much being accomplished in the breakout sessions. Several issues and actions were raised and will be addressed. Results and follow-up actions will be posted to the Base Camp Knowledge Management System Web site. The next base camp workshop will be held during the next ENFORCE.

Some Tips for Using Cable Fault Locator
Some Tips for Using Cable Fault Locator
Some tips of cable fault locator: the occurrence of cable fault is accompanied by the laying and use of cable. The positioning of cable fault is gradually increasing with the different laying methods of cable. Among them, the positioning and search of bridge, tunnel and open laying in ditch is relatively simple, and the positioning and search of direct burial is difficult. When the fault nature is simple, the cable fault locator adopts special cable fault location equipment, which can locate the fault within dozens of minutes. When the fault is special, it often takes 4-5 days or even longer to locate the fault. When using echo method for cable fault location, sometimes by transferring the fault phase and wiring mode, complex faults are often transformed into simple faults, and the fault location is quickly determined to win time for the emergency repair of on-site lines, which is of great significance to the power supply user department. Low voltage power cables are generally multi-core cables. After laying and continuous use, they generally show two core and multi-core phase to phase or phase to ground short circuit faults. Sometimes, when it is detected that the fault waveform collected by a core is not ideal, it can be considered to convert the wiring to other fault cores for fault waveform detection, which often has unexpected effects. The collected and detected waveforms will become more typical and regular, so the specific location of cable fault point can be determined quickly. During the long-term on-site measurement of cable customers, it is found that the fault of small cross-section copper core directly buried power cable (35mm2 and below) and aluminum core cable may be accompanied by short-circuit and wire breaking fault at the same time. During on-site detection, changing the short-circuit fault to wire breaking fault measurement according to the different fault nature of each fault core will often double everything with half the effort. For the medium voltage direct buried power cable with extruded armor as the inner lining, the fault is mostly caused by external mechanical damage. When the insulating core fails, the inner lining may have been damaged. In case of special cable insulation fault, it is difficult to collect waveform with professional cable fault instrument. It can be considered to use the acoustic method to apply the high-voltage pulse directly between the steel strip and copper shielding layer of the cable, which will often be fixed quickly. In the field measurement process, we also found that when using the acoustic measurement method to locate the fault point of low-voltage cable, when the high-voltage line and ground wire are connected between the bad phase and the metal shield or armor, the sound is very small, so the probe can not be used to listen to the fixed point, and the effect is not ideal. Through the actual listening side on site for many times, it is found that if the distance between the discharge ball gap is appropriately increased, and the high voltage and grounding wire are connected between the two phases of the fault, the discharge sound will become larger and the fault point will be determined quickly.
Power Cable Fault Location Method
Power Cable Fault Location Method
Fault location method of power cable: Aiming at the problem that it is more difficult to determine the fault location of buried power cable than overhead line, this paper selects a representative example of fault location process of 10 kV cable in case of high resistance fault, and introduces the method of locating and locating the fault point by using secondary pulse method according to the fault nature. For the high resistance fault during cable operation, first consult the relevant data of the cable and master the detailed information of the cable; Use multimeter and insulation resistance meter to judge the cable fault type, and determine the corresponding test method according to the fault type; Use the fault tester to test the length of the cable, check whether the test results are consistent with the data, and preliminarily determine the distance of the fault point; Finally, the secondary pulse method is used to accurately locate the fault point, find out the fault point, peel off the cable and find out the cause of the cable fault, so as to take corresponding preventive measures. This method is easy to master, especially for short-distance faults, the test waveform is easier to analyze, and the fault distance can be determined quickly, which makes the cable test more efficient and the fixed-point positioning time shorter. Power cable faults are complex and diverse, which can be divided into open faults and closed faults according to fault surface phenomena; According to the grounding phenomenon, it is divided into grounding fault, phase to phase fault and mixed fault; According to the fault location, it is divided into joint fault and cable body fault; According to the nature of resistance, it is divided into broken line fault, mixed line fault and mixed fault. Among them, mixed line fault is divided into low resistance fault, high resistance fault and flashover fault. 1. Fault detection methods for different cable faults, the common detection methods include low voltage pulse method, pulse current method, secondary pulse method, bridge method, pulse voltage method, etc. [3]. This paper only introduces the three commonly used detection methods. 2. Low voltage pulse method low voltage pulse method is suitable for detecting low resistance fault (short circuit fault with fault resistance less than 200 & omega;) and open circuit fault. It can also be used to measure the length of cable and the propagation speed of electromagnetic wave in cable, and distinguish the middle head, T-joint and terminal head of cable. 3. Pulse current method pulse current method generally includes impulse flash method and direct flash method. The linear current coupler is used to collect the current traveling wave signal in the cable and generate the fault test waveform, so as to judge the fault condition and measure the distance between fault points through the waveform. The direct flash method is used to detect flashover breakdown faults, that is, the resistance at the fault point is very high, and flashover breakdown faults will occur when the voltage is raised to a certain value with high-voltage test equipment. The impulse flashover method is also suitable for testing most flashover faults. Because the waveform of the direct flashover method is relatively simple and it is easy to obtain more accurate results, the direct flashover method should be used as much as possible. 4. Secondary pulse method with the cooperation of high voltage signal generator and secondary pulse signal coupler, the secondary pulse method can be used to measure the fault distance of high resistance and flashover faults. The waveform measured by this method is simpler and easy to identify.
Model Prototype Exercise: Handheld Electric Screwdriver
Model Prototype Exercise: Handheld Electric Screwdriver
To practice designing 3D low-fidelity prototypes, I was tasked to prototype an OXO handheld electric screwdriver as a new opportunity to expand their business into new product lines.Designing for OXOs Brand IdentityBefore sketching out design ideas, I wanted to familiarize myself with the OXO brand, hoping that the form of my design will match with OXOs brand identity. OXO incorporates comfortable and easy to use tools, while also applying simple,universal design. When I was sketching, I wanted to prioritize comfort, which is why the designs for the screwdriver include a hand grip area for the user to comfortably hold the screwdriver. I also attempted to emulate the simple designs of OXO, because the interfaces to be as minimalist as possible.Additionally, the sketches addressed the product requirements of a fluid speed control, a automatic screw driver selection (shape and size), direction mechanism (screwing in vs. screwing out), and a progress digital readout (number of screws in and out).PrototypeI created a handheld electric screwdriver prototype that is 6 inches long. With rocks and Easter eggs filled with rice inside, the prototype weighs one pound, emulating the actual weight of the product. Shape & FormI wanted the shape and form of the screwdriver to be comfortable and intuitive for the user. The handle on the screwdriver is slightly curved to emulate the natural grip when holding an object around your hand. I also included tape around the area to represent different material that would be incorporated for comfort. Additionally the handle is suitable for left-handed users or right-handed users.FunctionalityThere are several functionalities that make the prototype, including speed control, screw driver shape/size selection, screw driver direction, and a digital readout component. The screwdriver will also have a rechargeable battery. Fluid Speed Control Mechanism: I incorporated a fluid speed control under tucked in the handle for easy access to change the speed of the screwdriver while holding it at the same time. The sensor will capture the pressure of the grip and change the speed accordingly. The white thumbtack shown in the left image above is located where ones index finger would be, a intuitive hold and position to be controlling the speed. Screw Driver Selection Mechanism (shape/size): For the screw driver shape and size selection, this screwdriver supports 2 different head changes (Phillips or flat) and 5 different sizes. This screw driver shape and size is presented on a touch screen, where the user can tap to select different heads and sizes. After the user will press set for the screwdriver to automatically change shape/size. This interface is above the gripped area to avoid accidental switches in screw driver. Additionally the interface faces the user when they hold onto the screwdriver, allowing for easy visibility of the current setting of the screwdriver.Screw Driver Direction Mechanism: The screw driver direction mechanism is located on the side of the screwdriver with a slider mechanism to change the direction based on if the user is screwing in versus out. Digital Readout Component: The digital readout component shows the number of screw in and out below the direction mechanism. The reset button allows for the user to set the count back to 0.Rechargeable Battery: The screwdriver is rechargeable and the battery is placed inside the bottom of the screwdriver. AnalysisAfter finalizing the prototype, my peer members were able to give critiques and I was able to conduct one in-depth user test on all functionality. Click on the link below to view a snippet of the user test.What went well?Many users enjoyed the fit and weight of the prototype, explaining that the curved form of the screwdriver fit well with their grip and how they would intuitively hold the screwdriver. Users found the reset button on the count of the number of screws in and out practical and functional even thought it wasnt a product requirement.The speed control was intuitive for everyone, knowing that the harder they pressed the faster the head would turn. All users found the button placed in a comfortable position where their index finger was. The placement of the rechargeable battery was intuitive for all users.What needed improvement?Many users were confused with the digital readout component that indicates the count of screws in and out. Manyusers were unable to initially understand what the numbers stood for. There was uncertainty with the set button, expressing confusion on the ordering of changing the heads of the screwdriver. If the set button should be pressed before or after selecting the shape and size.The placement of the reset button may get in the way when gripping the screwdriver, possibly causing unintentionally reset of the digital readout. Additionally there was no way to reset only one of the digital readout numbers. So if a user wanted to reset only the number of screws in, this would not be possible.Takeaways & Next StepsOverall based on this analysis, the most effective component of the prototype was the shape/form of the screwdriver as well as the fluid speed control mechanisms. Both were praised and intuitive for users. However, the least effective component was the interface of the digital readout component. By using icons paired with labels of in and out the digital readout component can be more clear on what is being represented. Additionally if the slider is placed between the label and the actual readout component, the label would be on the top, possibly better indicating what the digital readout is and what the in and out slider does.Next steps would be to improve on the interfaces of the digital readout component, since this was the least effective functionality. After improving on the new interface, the next step is to do another round of critique and user testing. RELATED QUESTION Which is the best natural face mask for dark and oily skin?

Introduction to Underground Pipeline Detector
Introduction to Underground Pipeline Detector
Classification of underground pipeline detectors 1. One category is to detect metal pipelines, electric / optical cables and some non-metallic pipelines with metal marker lines by using the principle of electromagnetic induction. This category is referred to as pipeline detectors for short. Advantages: fast detection speed, simple and intuitive, convenient operation and high sensitivity. Disadvantages: (underground pipeline detector) when detecting non-metallic pipelines, non-metallic probes must be used. This method is laborious and needs to invade the interior of the pipeline. 2. The other is to use electromagnetic wave to detect underground pipelines of all materials, which can also be used to find underground buried objects, commonly known as radar, also known as pipeline radar. Advantages: (underground pipeline detector) can detect pipelines of all materials. Disadvantages: high requirements for environment, poor sounding ability (it is difficult to check pipelines with deep buried depth), and high requirements for operator quality and experience. Any instrument is not superior and needs to be used together in order to give full play to their excellence. Traditionally, pipeline detectors only refer to pipeline detectors using the principle of electromagnetic induction, and also use * many instruments.
