How to Carry Out Fault Location of High Voltage Cable
How to Carry Out Fault Location of High Voltage Cable
The speed of China's economic development is obvious to all. The country's economic development has driven the development of all walks of life, and all kinds of construction work has been strengthened. The construction scale of national power grid is expanding. Although China has also popularized and applied multi-channel high-voltage cable technology, its structure is becoming more and more complex, resulting in multi-channel failure of high-voltage cables. Next, we discuss the problem of fault location of high voltage cable. High voltage power transmission lines have been affected by environmental changes in recent years. The insulation layer of cables is damp due to rainy weather and ponding, the overall overheating in the process of cable use, and the high voltage of cables will not only affect people's power consumption experience, but also cause irreparable loss of economic benefits to relevant power consumption enterprises. How to accurately locate and quickly remedy the fault of multi branch high-voltage transmission line cable has become the focus of power supply departments and power companies. 1、 The construction and analysis of cable simulation model great changes have taken place in the current natural environment, and the natural wear of cable lines is becoming more and more serious in the harsh natural environment. Therefore, the stable and continuous operation of the cable requires the cable protective layer to protect the cable, and the cable protective layer usually plays a key role in protecting the cable. We need to consider the cable, so we should select the power supply equipment matching the cable in the test. However, we should note that when setting the data of the power supply, we need to select the conventional settings of the circuit and resistance, and do not exceed the range borne by the cable. 2、 Simulation and analysis of two-t lines the application of two-t lines is an innovative technology for today's multi branch cable erection, but no country can widely use this technology. We can evaluate the design idea, design scheme, design results and the effect after being put into use in a small scale. We can improve the cable technology in some large cities and areas with complete urban power grid construction. We can transform the original main power supply line into a power supply line of two t lines. If we use this technology, we can increase the investment of the corresponding part in the project and complete it as soon as possible. 3、 Firstly, when the fault location is in Section D, set the fault point in phase a of Section D and carry out the simulation process test. Based on the grounding wire at the beginning of a section, it is concluded that after a problem occurs, the current has a continuous transient process. Then, the metal sheath current that is slowly stable and connected to the fault is large, and the high amplitude reaches 5A. At the same time, the large amplitude of the non fault phase also reaches 1 A. there is no great difference between the current wave detected by this stage and the normal grounding wire. The main route of fault location of high-voltage cable and the route of fault section are cross connected, and the attenuation amplitude of high-frequency voltage will appear after fault. If the insulation layer in the cable breaks down, we can measure the grounding current in different sections and the attenuation amplitude of high-frequency voltage, and analyze the location of cable accident from the measured data.

What Should We Pay Attention to When Using Live Cable Identifier
What Should We Pay Attention to When Using Live Cable Identifier
The emergence of electricity has broken people's original lighting mode and provided us with a convenient and comfortable living environment. Cable has the function of transmitting electric energy and plays a very important role in life. The demand for electricity is so great that sometimes the cable will inevitably have problems. Live cable identification instrument is one of the commonly used fault detection equipment. 1. The operator shall read the operation manual in advance, master the function, working method and work preparation of the instrument, and carry out correct test requirements. 2. Before the test, disconnect both ends of the tested wire with armored grounding, and ground the far end (one end) of the core wire. 3. The two output wires of the cable identifier shall be clamped in red on the core wire of the tested wire and grounded in black. 4. Before turning on the transmitter, the output adjustment knob must be turned counterclockwise to zero before starting. Slowly adjust the output adjustment knob to make the output reach 5a-15a (usually adjust the adjustment knob in the range of two-thirds). If the grounding resistance of the distribution station system is greater than 4 ohms, the output current is less than 8a, and the receiver instrument head can work normally, as long as it can deflect in the positive and negative directions. 5. Note: during field use, if the grounding resistance is too small and the output adjustment knob of the transmitter is zero in one clock cycle, the output current will be very large, and there is a protective circuit action in the transmitter (indicating a small swing of the plug). In Article 2, in the actual test, there are more than two connections between the two transformer chambers between the same cable conduit and other cables, The grounding resistance is connected because there are other armored cables in operation, and the change is very small, even close to zero. If the output current of the transmitter is too large and there is a protection circuit, the resistance can be tested in series in the transmitter loop test. After the test, the temperature of the test resistance is very high. Note that other 1-2 ohm resistors greater than 20W can also be used instead of the test resistance. 6. Before identifying the cable on site, please calibrate the receiver of the live cable identification instrument at the beginning of the wire according to the instrument calibration requirements in the instruction manual. 7. Standard for cable field identification: when the sensor is pasted on one of the cables for test, the header of the receiver will lean to one side and swing more. When testing on other cables (keeping the clamping direction of the sensor the same), the receiver instrument head will lean to the other side and swing less. The cable with the receiver instrument head leaning to one side and swinging sharply is the cable to be identified.
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.

Design of Consumptive Optical Fiber High Temperature Measuring Instrument
Design of Consumptive Optical Fiber High Temperature Measuring Instrument
1 IntroductionHigh temperature measurement plays an important role in aerospace, materials, energy, chemical industry, metallurgy and other fields. At present, in high temperature measurement, according to whether the measuring probe is in contact with the measured object, the temperature measuring instruments are divided into contact and non-contact.With the emergence of optical fiber technology, it provides conditions for the realization of contact temperature measurement. The contact optical fiber temperature measurement adopts a long quartz optical fiber as the temperature measurement probe and transmission system to keep the instrument away from the site with bad environment. At the same time, the optical fiber optical path is not affected by the environmental atmosphere, which greatly improves the environmental adaptability of the temperature measurement system. However, because the probe adopts the general radiation receiving principle, it is still difficult to solve the problem of emissivity. In order to overcome this problem, the principle of ash body temperature measurement is proposed. The colorimetric method can greatly reduce the influence of emissivity on the temperature measurement results. Under the best conditions, the influence can be reduced to zero. The advantage of such temperature measurement is that the temperature measurement response speed is fast, and the response speed is about 10s [3].The consumable optical fiber high temperature measuring instrument developed in this paper overcomes the above shortcomings and is a new method to measure the temperature of molten metal. Its temperature measurement accuracy is the same as that of the consumption thermocouple, but the temperature measurement cost is greatly reduced, which has great economic benefits and can completely replace the consumption thermocouple.2 principle of colorimetric temperature measurementColorimetric temperature measurement is a method to determine the temperature of an object by measuring the ratio of the radiance of the object at two different wavelengths. Its characteristic is that it can eliminate the interference caused by atmospheric, smoke, dust, ambient temperature and other factors on the measurement path.3 selection of working wavelengthAs can be seen from equation (3), it is very important to correctly select the wavelength and wavelength. Generally, the spectral radiance of the measured object is related to wavelength and temperature, as shown in Figure 1. The ordinate in the figure represents the radiation brightness of the blackbody, the abscissa represents the wavelength, and the temperature of the curve is getting higher and higher from bottom to top.From the curve in the figure, we can see several characteristics of blackbody radiation: (1) the total radiance increases rapidly with the increase of temperature. The higher the temperature, the greater the spectral radiance; (2) When the temperature is constant, the spectral radiance changes according to a certain law with different wavelengths, and the curve has a maximum value. The wavelength here is defined as that when the wavelength is less than, the radiance increases with the increase of the wavelength, and when the wavelength is less than, the change law is opposite; (3) When the temperature increases, the peak wavelength of spectral radiance moves to the short wave direction, the radiance of the object increases, and the luminous color also changes.The wavelength range is preliminarily set at 800 1000 nm, and there is no main absorption band of water vapor in this range, which can reduce the measurement error. When it is 800nm and 1000nm respectively, the relative sensitivity curve is shown in Fig. 2. The relative sensitivity of curve 1 in the figure is high. Therefore, it can be seen that it should be near 800nm. According to the relationship between the spectral response of the photodetector and temperature, it is required to have a good linear relationship. According to the linear relationship, it is better to take it near 950nm.After the experiment, the final choice = 890nm, = 940nm, the colorimetric temperature measurement effect is better.Fig. 2 relation curve between relative sensitivity and temperature

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.

How to Diagnose and Solve Cable Leakage with Cable Fault Tester
How to Diagnose and Solve Cable Leakage with Cable Fault Tester
How can the cable fault tester diagnose and solve the cable leakage? As the main cable fault, when the power cable leaks to the earth, it will produce a strong to weak directed electric field gradient around the fault point on the ground. The amplitude and direction of the signal can be measured by Bao Shun Tong cable fault measuring equipment along the cable path. Before and after the fault point, the direction pointed by the galvanometer pointer is opposite, so as to find the fault point of the cable and achieve the purpose of accurate positioning. 1. Cable fault diagnosis depends on the nature of the fault. Cable fault can be divided into low resistance grounding or short circuit fault, high resistance grounding or short circuit fault, wire break fault, wire break and grounding fault and flashover fault. Cable fault diagnosis can determine the type and severity of cable fault, and it is also convenient for testers to test it with different test methods according to different fault types. For example, for high resistance faults, the impulse flash method can be used to locate the fault location. 2. Cable fault location. Cable fault location is also called rough measurement. There are two rough measurement and location methods: electric bridge method and wave reflection method. At present, wave reflection locator is more popular. However, several cable faults are difficult to find by wave reflection method, such as insulation defect points of high-voltage cable sheath, steel tape armored low-pressure cable, PVC cable and short cable can not be located. In addition, some high breakdown points cannot be broken down under impulse voltage and are difficult to locate. 3. Cable fault point. It is also called precise measurement. The cable fault can be accurately fixed through the methods of acoustics, electromagnetism, electronic signal processing and electronic cancellation theory. The LCD can display the sound pulse, magnetic pulse and the distance between the fault point and the probe test point at the same time. At present, the cable fault can be accurately fixed by the following four methods: (1) Acoustic measurement method: the high-voltage pulse generator discharges the fault cable, the fault point generates an arc and generates a discharge sound. When the cable is directly buried, it generates a seismic wave. The acoustic probe of the pointing instrument picks up the seismic wave signal and amplifies it and outputs it through the headset or meter head. (2) Step voltage method: it is mainly aimed at the fixed point of outer sheath grounding fault with requirements for cable outer sheath insulation. Now, step voltage method can also be used for the fixed point of some directly buried unarmored low-voltage cables and wire core grounding fault. (3) Electromagnetic method and audio method: fix the point with electromagnetic wave or audio method, that is, determine the fault point by using the change of electromagnetic wave signal or audio signal at the front and rear points of cable fault. (4) Acoustic magnetic synchronization method of cable fault tester: it is the comprehensive application of acoustic measurement method and electromagnetic wave method. Then, according to the above operation methods, we believe that the fault point can be found soon, and we can quickly repair and restore the normal operation of power.
Working Principle of Live Cable Identification Instrument
Working Principle of Live Cable Identification Instrument
As the running live cable is not allowed to damage any grounding wire and other connecting wires, nor is it allowed to directly add the output signal of the live cable identifier transmitter to the cable phase line with high voltage. Two difficult problems need to be solved for live cable identification. One is how to couple the cable identification signal to the cable; Second, the coupled signal is generally small, and the operating cable may have 50Hz power frequency electromagnetic interference composed of 50Hz unbalanced current, induced 50Hz interference current, cable distributed capacitance current, etc. the high-sensitivity receiving caliper has the problem of how to resist 50Hz power frequency interference. The charged cable identification instrument developed by US adopts single chip microcomputer coding and decoding technology and PSK technology widely used in the field of communication. The phase coded signal with an average value of 0 is transmitted on the transmitting caliper, and the single chip microcomputer in the receiving caliper performs phase identification after filtering the received signal by hardware and software. When the receiving caliper cards the cable according to the current direction, the identified cable ammeter deviates to the right, accompanied by audible and visual indication. The current direction of other cables is opposite to that of the identified cable, and the ammeter pointer deviates to the left. No audible and visual indication. This reflects the uniqueness of the identified target cable. It is easy to distinguish the identified cable from multiple cables. In addition, since the signal current strength on the identified cable is the same throughout the line, the electromagnetic signal strength received by the receiving caliper along the cable is the same. In principle, the identified cable is not limited by the length of the identified cable.

Bootcamp 487: Moving to a New Pc Part 3
Bootcamp 487: Moving to a New Pc Part 3
Keep abreast of the latest issues in computer technology with Rick MayburyThe absolute quickest and simplest method of transferring data from one PC to another is to 'slave' the old drive. Depending on your level of expertise it should only take around fifteen to twenty minutes and when you next boot up your new PC all of your old files will be accessible, ready to be used or copied to your new hard drive. It really is that easy, however, I wouldn't recommend trying it if you are uncomfortable about poking around inside your PCs or you have any doubts about your DIY skills. If so you should wait for the next two episodes of Boot Camp, which will be looking at totally non-invasive data transfer methods using removable media and cables. It's virtually impossible to get an electric shock from a desktop PC; mains voltages are safely contained inside an earthed metal box and none of the cables emerging from the box carry more than 12 volts. Nevertheless you should unplug both PCs from the mains before you open the lids, we don't want any accidents, do we? Electronic components are remarkably robust but there is a very small chance you could damage something through a static discharge from your body or clothing. Although the risk is very low it doesn't hurt to briefly touch a nearby radiator, metal water pipe or earthed metal appliance, before you open up your PC. If you are really worried you can buy anti-static wrist straps from PC Suppliers and Maplin Electronics for a few poundsStart by opening up your old PC, on most models there will be only one hard drive and it will normally have two cables plugged into the back of it, one for the power supply with four coloured wires (red, two black and yellow). The other one will be a flat 'ribbon' connector that carries the data. Gently remove both plugs, they may be a little stiff, so don't tug on the cables or you may damage them. Tuck the cables out of the way and remove the four mounting screws - two each side. Avoid touching the connectors or the circuit boards on the underside; hold it by the sides and once the screws are out slide the drive out from its 'bay'.Bootcamp ArchiveNext set the drive to 'slave' mode. On most hard drives there will be a printed label showing the positions of the 'jumpers' for Master, Slave and Cable Select (CS). The jumpers are small connectors that bridge sets of pins and they're normally located on the rear of the drive. Your old drive should be in Master mode, so you can use the current positions for orientation and reference. Use a small pair of tweezers or thin long-nosed pliers to change the jumper(s) to the Slave setting. Now you can remove the cover from your new PC and locate a spare hard drive bay. If you are very lucky you will see a spare set of data and power cables nearby, though nowadays most new PCs now use SATA type drives, which use much smaller data cables. It's not a problem, though, and most motherboards have at least one 'legacy' ATA/IDE socket that you can use. If you don't have a spare ribbon cable you can borrow the one from your old PC (see also this week's Top Tip). It's a good idea to do a dry run first and fit the old drive into it's new home. If you have to move cables out of the way do it carefully so as not to loosen any connections. One you are happy with the fitting plug in the data and power cables. Note that both plugs are 'keyed', so they only fit one way around. The plugs should seat fairly easily so do not press too hard and be especially careful not to bend the pins on the data cable socket. If you are using the data cable from your old PC don't forget to connect the other end to the IDE socket on the motherboard..Fit the drive mounting screws and give all of the nearby cables and connectors a final check to make sure you haven't dislodged anything. Refit the case lid and switch on. Windows will boot up as normal and your old drive will be recognised and automatically assigned the next available drive letter. If so you can get on with the job of transferring your data using My Computer or Windows Explorer. If the drive doesn't show up in Explorer then here's a few troubleshooting tips.Switch off, disconnect form the mains, open the lid and double-check the power and data cables. If everything looks okay put the lid back on and boot into the PC's BIOS program. (Refer to the user or motherboard manual for the correct combination of keys to press at start-up). Run the drive setup/configuration utility and check that it has been recognised. On some BIOS there may be a 'switch' to enable the IDE connector. If the drive still isn't found then there is a problem with the data or power connections or the drive is faulty.ANTI STATIC WRIST STRAP Conductive pad, attached to a strap that fits around the user's wrist, attached to a resistor and a wire that clips onto a metal radiator or water pipe, designed to safely dissipate static chargesBIOSBasic Input Output System: diagnostic and configuration program stored in a microchip memory on the PC motherboard that checks the PC hardware before the operating system is loadedCABLE SELECT Special type of data cable used by some PC manufacturers that automatically selects Master or Slave mode SATA drives use a different type of power connector that will not fit ATA/IDE drives, however, most PC power supplies have at least one spare older-style 4-pin power connector as these are still widely used by CD and DVD drives. In the unlikely event a spare connector isn't available you can use a SATA to IDE power adaptor lead. These can be obtained from PC suppliers and typically cost around £2 - £3.Don't forget, there's a full archive of previous Boot Camp Top Tips at www.pctoptips.co.uk
