Brief Introduction of Cable Fault Locator
Brief Introduction of Cable Fault Locator
The basic function of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems. It is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.

What Are the Principles and Advantages of High Voltage Bridge Method
What Are the Principles and Advantages of High Voltage Bridge Method
What is a high voltage bridge? Designed based on the principle of Murray bridge, it is applicable to the location of breakdown points (low resistance, high resistance and flashover breakdown) of various wires and cables after laying and points without breakdown but with low insulation resistance: for example, the insulation defect points with low cable resistance but without breakdown under operating voltage are found with a megger. Of course, it can also be used to locate the defect points of various cables in the cable factory. There are two methods of cable fault location in rough measurement: electric bridge method and wave reflection method. At present, wave reflection locator is more popular. Its disadvantages are: the field wiring of some instruments is complex and there is a positioning blind area. When the waveform is not typical, the positioning personnel are required to master the instrument and be experienced to distinguish the pulse waveform. There are several cable faults that are difficult to find by wave reflection method: for example, insulation defect points of high-voltage cable sheath, steel tape armored low-pressure cable, PVC cable, no reflected wave, unable to locate. Short cable, unable to locate. Some high breakdown points cannot be broken down under impulse voltage and are difficult to locate. The high-voltage bridge cable fault tester contains a high-frequency, high-voltage and constant current source, which solves the interference problem of the power supply to the high-sensitivity amplification of the bridge. The power supply and the bridge are integrated. The measuring cable is a special high-voltage cable, which adopts the resistance measurement principle of four terminal method, with high positioning accuracy. The bridge is placed on the high voltage side and the operating button is safely grounded. The limitation of the bridge method for high resistance positioning is solved, and the characteristics of no blind area, accuracy and convenience of the bridge method can be brought into play. Murray principle in high voltage bridge: Murray in Chinese means Wheatstone, Wheatstone bridge (also known as single arm bridge). The universal Wheatstone bridge resistors R1, R2, R3 and R4 are called the four arms of the bridge. G is the galvanometer to check whether there is current in the branch where it is located. When G has no current, it is called that the bridge is balanced. When balancing, the resistance values of the four arms meet a simple relationship, which can be used to measure the resistance. When G has no current, it is said that the bridge reaches balance. When balancing, the resistance values of the four arms meet a simple relationship. Using this relationship, the resistance of Murray bridge can be measured. Advantages: 1. Murray bridge balancing method has no test blind area, which is used to judge the short cable and the breakdown point near the cable end. 2. Murray bridge method only requires the uniformity of cable phase resistance. Cables with poor traveling wave transmission characteristics, such as PVC low-voltage cables with large dielectric loss, can effectively judge the short cable and the breakdown point near the end by combining the current source with Murray bridge technology, so that steel tape armored low-pressure cables and PVC cables can have positioning and no blind area search.
A Brief Guide to Selecting Cable Length Testers
A Brief Guide to Selecting Cable Length Testers
The LinkRunner LTRA offers a variety of cable testing techniques, including TDR, wiremapping, office identification and toning. The LTRA is designed to help troubleshoot wiring problems such as excessive cable routing, cable breaks, wall panels, patch panels, etc. It uses a combination of TDR and resistance measurements to map the wire, measure cable length and detect anomalies such as short, open or split pairs.The LRAT can measure an accurate cable length of 100 m or less with an accuracy of plus or minus 2 m. It can also be used to test terminated cables connected to an internal cable mapping port (WMAP) or an external cable identification accessory, as well as undermined and open cables. For pre-assembled and non-assembled cables, the fault detection is accurate to within 0.8 m of the error distance.This tester is a wiremapper that checks connections for CAT 5E / 6 certification, but can also test performance at higher frequencies. The threshold for the low voltage resistance is set insulated for 5 mO to a contact resistance of 0.1 O. This is measured with an embedded resistance at 100 O (1 mO x 1) to achieve an accuracy of less than -0.1 o (5 mO).In fact, certification testers can test wire diagrams, length attenuation, and crosstalk from one connection to another, helping you troubleshoot and save the results in a printed report for the customer. Cable certification testers are automated, so it's so easy to get a pass or fail at the touch of a button. Installers use certification testers to test cables that are being laid.There are a large number of cable testers on the market today, which means that there may be the right device for your purposes. To help you find the best network cable tester for your use I have compiled a list of test products that work well. As someone with extensive experience as an electrician, I can say that the Elegiant Network Cable Tester is the best tool for testing cable connections.I came across the Elegiant Network Cable Tester while working on establishing a LAN connection for a local company. As a consumer, I used the handheld network cable tester with RJ11, RJ12, RJ45 for the Cat 3 types Cat 5E, Cat 6 and Cat 6A. The broad compatibility of the device does not complicate your work in the analysis of cable connections.Cable Prowler (tm) provides complete cable testing for all categories of network, coaxial and telephone cables. Selecting, selecting and purchasing a suitable network cable tester is a complicated and challenging task. Purchasing the right network cable tester can save you a lot of inconvenience and trouble.Includes low-voltage and high-voltage subsystems, HVX-compliant automation, enabling extended testing of insulation resistance, dielectric breakthrough, Zener diode breakthrough, voltage upgrade, 4-wire measurements, and advanced measurements. With the changing landscape of corporate cabling, there is a demand for testing equipment you can rely on. Hopefully this article has helped you choose the best network cable tester for your profession and field of work.Advanced measurement options provide increased x5 / 2 wire resistance resolution for backplane, complex networks, capacitors, wire pairs, capacitors, twist pairs, and cable length testing. Copper remains the first choice for telephone data and video lines. Integrated Intellitone digital / analog tones are located on the cable or wire pair in the active network.It is an expensive device that requires trained operators and many failures due to problems with the wirecard. Other crews use low-cost cable ties to ensure the connections are correct before the certification tester is turned on. Instead of letting the crew find and fix their own wiremap problems, tests and fixes can be made before the cable is installed, and tester costs are not wasted on simple problems.

How to Quickly Locate Cable Faults
How to Quickly Locate Cable Faults
With the different cable laying methods, the difficulty of cable fault location is gradually increasing. 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 the most difficult. When the fault nature is simple, the special cable fault location equipment can be used to 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. How to quickly locate cable faults? 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.

Today, I would like to share with you seven tips on using and maintaining electric screwdrivers.Five tips on Maintenance Power ScrewdriverRead the instructions and operate the power screwdriver according to the specificationsThe use of the process should pay attention to the motor size of power screwdriver. Dont operate blindly in case of excess of workload and damage to the power screwdriver. For example, like this screwdriver with torque control its torque range is 3070 kf.cm. It can only tighten objects within 3070 kg but not 80 kg. Because its torque value does not meet the requirements, which will damage the power screwdriver and reduce its life. [caption4. During the using can not be directly adjusted from the lowest torque to the highest torque or from the highest torque to the lowest torque, this is easy to cause clutch and torque thimble off. Thus reducing the service life of electric screwdrivers. Before using the power screwdriver you should tighten the fixing ring (or torque sheath) of. Both ends of the power cable should be symmetrical with the socket hole of the power supply and the electric driver and tighten the nut of the power cable.6, power screwdriver should be kept well, do not allow the corrosive liquid to enter5. Please keep the repair card of the power screwdriverBrushless vs. power screwdriverThe carbon brush life of the electric screwdriver is about 1000 hours. Of course using the original carbon brush, in addition to the power screwdriver to maintain. I suggest buying a brushless electric screwdriver, which is maintenance-free. Brushless power screwdriver will not produce an electric spark, strong anti-interference abilityAlthough the power screwdriver and common screwdrivers are the same, the operation method is simple, but the use of skill is not in place, can cause certain damage to the power screwdriver, so should ensure correct use method and maintenance skill, increase its service life. Brushless power screwdriver will not produce an electric spark, strong anti-interference ability. Brushless motor without carbon brush can reduce noise and wear.
