Fault Location of Power Cable and Fault Location of High Resistance Cable
Fault Location of Power Cable and Fault Location of High Resistance Cable
Power cable fault and high resistance cable fault are common problems of cable fault, and also belong to medium and high frequency problems of cable fault. Below, the author analyzes and writes the methods of cable fault location of these two cables, hoping to have a certain reference for everyone in case of cable fault. 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.
What Are the Common Faults and Discrimination Methods of Cable Fault Tester
What Are the Common Faults and Discrimination Methods of Cable Fault Tester
1、 Cable fault type power cable fault is mainly due to mechanical damage, insulation aging, low construction quality, overvoltage, etc. The commonly used cables are cross-linked ethylene, non dripping oil type, oil immersed paper type, polyvinyl chloride and unknown type. According to the nature of cable fault, they can be divided into low resistance grounding or short circuit fault, high resistance grounding or short circuit fault, disconnection fault, disconnection and grounding fault and flashover fault. 2、 Firstly, we need a megger to measure the insulation resistance of each phase, and judge the fault type according to different insulation resistance values. 1. When we measure that the insulation resistance of the cable to the ground is lower than 100k Ω, it is a low resistance grounding fault. 2. When we measure that the insulation resistance of the cable to the ground deviates from the normal value or is higher than 100k Ω, it is a high-voltage cable fault. 3. When the ground resistance of the measuring cable is high or normal, conduct multiple tests on the conductor to check whether there is a wire break. If there is a wire break fault. 4. When the conductor of each core or multiple cores of the measuring cable is discontinuous, and then after multiple core to ground measurement, judge which type of the above three faults. 5. Flashover fault basically occurs in preventive voltage withstand test, cable terminal and middle joint. Sometimes flashover occurs many times, but the interval is a few seconds or minutes. 3、 Cable fault tester to find out cable fault methods: 1. With high-voltage equipment, it has the traditional impact high-voltage flashover method and low-voltage pulse method. 2. 2. Any high resistance fault presents simple waveform characteristics similar to low voltage pulse short circuit fault, which is very easy to interpret. 3. The cable fault tester finds the fault point through four main parts: cable fault location host, locator, Pathfinder and high-voltage signal generator.

Do You Know How to Choose a Suitable Cable Fault Tester
Do You Know How to Choose a Suitable Cable Fault Tester
Cable fault tester is one of the common equipment to detect cable fault. It has stable performance, can quickly and accurately find out the fault point, and the maintenance personnel can quickly carry out maintenance work, which greatly provides work efficiency. The purchase of cable fault tester is also a problem valued by many friends. Next, we will focus on the precautions for purchase. Another situation of the power supply analysis of the damage of the cable fault tester in recent years, 80% of which is due to the poor wiring or wrong wiring during high-voltage impulse flash, resulting in the damage of the instrument. If the battery is used for power supply, even if the high-voltage is connected in series, it will not form a loop to the earth and can only cause the common mode effect, so as to completely avoid the occurrence of machine damage accidents. Problems of collector and notebook computer: the test scheme of collector notebook is a design scheme proposed by the company in 1996 and put into practice. In 1997, the cable fault test and management system was launched. Through several years of market use, it seems that it does not adapt to China's national conditions. At that time, the principle considered in the design was to give users a good tool and strong data processing ability. But for the following reasons. At present, it has been discontinued. Reasons why notebook collector is not suitable for on-site cable fault test: 1. The on-site environment is not suitable for the use of notebook computers. Generally speaking, notebook computers are relatively delicate and suitable for office or business travel. However, most of the cable fault tests are in substations or outdoors, with large dust, large interference and complex environment, which will greatly shorten the service life of notebook computers. And the sampling waveform is not good. 2. Generally, the switching power supply of notebook computer can only be used when the impact of power grid is small. When the high-voltage impulse flash of cable fault is carried out, the power grid fluctuates greatly, which is very easy to cause damage to the power supply of notebook computer. Therefore, when testing the high-voltage impulse flash of notebook computer, it is emphasized to disconnect the charging power supply and test with the internal battery. 3. In the cable fault test, the high voltage string into the tester is a common problem due to the wiring problem. The impact resistance of the notebook computer is very weak. High voltage enters the notebook computer through the test line collector, which will eventually lead to the damage of the notebook computer interface. Such lessons have been encountered in several cases in our customers. Although current sampling can improve the safety of equipment at present, current sampling is chaotic for short-range fault waveform and difficult to identify, so it is often misjudged when testing short-range fault. 4. Computer viruses will affect the normal use of the equipment. Such problems seem to have nothing to do with our equipment, but users will inevitably make the computer impacted by various computer viruses when using the computer. When there is a problem with the cable, there will be various problems when taking it out for use, and it will not work normally. This results in delayed power supply. At present, the cable fault tester with advanced performance should be equipped with an interface for communication with the computer. Select the cable fault tester with computer interface and test with the cable fault tester on site. After the test, the test waveform needs to be saved and uploaded to the laptop or other computers for archiving, analysis, production of test reports, etc. It should be the best procurement scheme.
In Case of These Six Cable Faults, It's Right to Choose It for Detection
In Case of These Six Cable Faults, It's Right to Choose It for Detection
With the characteristics of faster inspection speed and high precision of cable fault detector (also known as cable fault detector, cable fault locator and cable fault tester), it has won the favor of many customers. Many powerful enterprises will purchase a set of cable fault detector equipment to ensure the smooth operation of cables in the industrial zone. For equipment with these 6 kinds of cable faults, please choose this cost-effective cable fault tester. 1. Low resistance fault, cable insulation material is damaged and grounding fault occurs. 2. In case of open circuit fault, the continuity of the metal part of the cable is damaged, resulting in wire breakage, and the insulating material at the fault point is also damaged to varying degrees. 3. High resistance fault, cable insulation material is damaged and grounding fault occurs. 4. Flashover fault: the insulating material of the cable is damaged, resulting in flashover fault. 5. Breakdown fault: in actual work, the cable insulation damage event triggered by preventive test is commonly referred to as cable breakdown. 6. Operation fault refers to the cable fault determined by eliminating the possibility of faults of other power elements when voltage fluctuation occurs in the high-voltage secondary circuit of cable feeders, motor and transformer during the operation of plant power system or grounding signal is found (grounding tripping occurs in power elements with grounding protection).
How to Quickly Detect the Fault Point of Low Voltage Cable
How to Quickly Detect the Fault Point of Low Voltage Cable
In many years of specific work, people have found that there are many differences between the common faults of high-voltage cables and low-voltage cables. Most of the faults of high-voltage cables are dominated by common faults of operation, and most of them are common faults of high resistance, which can be divided into leakage and flashover; The common faults of cable can only be led, short circuit and open circuit (naturally, high-voltage cable also includes these three conditions). In addition, the cable also has the following characteristics in the whole process of specific application: 1. The laying is blind, and the relative path is not very clear. 2. When laying, it is not buried after filling sand and bricks like high-voltage cables. On the contrary, the buried depth is shallow, which is easy to be damaged by external forces and common faults occur. 3. Cables are generally short, ranging from tens of meters to 500 meters, unlike high-voltage cables, which are usually 500 meters to many kilometers. 4. The compressive strength of the insulating layer is low. When solving common faults and making connectors, the processing technology is relatively simple. 5. Most cables are often burnt and damaged at common fault points. The common fault point is that there is no mark on the surface of the cable, which is very rare. ⒍ the required load changes greatly, and the two colors are usually unbalanced, which is very easy to get hot, resulting in common faults. Considering the above characteristics of the cable and the proposals clearly put forward by many customers and the specific application status of people in each region, the scientific research staff has successfully developed and designed the DW cable fault test mobile phone positioning system: the system software includes two parts: rangefinder and detector. The range finder of hn-213x system software is a completely intelligent system and personalized design scheme. It automatically detects the cable fault point without manual service, analyzes the common fault wave type, and immediately gives the distance between common fault points and common fault characteristics. The rechargeable battery power supply system is selected, which is convenient for field work, small in size, light in weight, easy to use, and does not need all auxiliary machinery and equipment. The cable fault detector of hn-213x system software is an instrument and equipment for simultaneous and accurate positioning and detection of the laying relative path, buried depth and common fault points of directly buried cables. Because it is a mobile phone positioning system for common cable faults based on the magnetic effect of current and the basic principle of step voltage, it mostly considers all standards of cable fault test. This kind of detection system software has many advantages compared with the cable fault detector based on the impulse flash method: 1. A variety of test standards are integrated and the results are mutually certified to clarify the uniqueness of common fault points. 2. Small size, light weight, easy operation by one person, no auxiliary machinery and equipment. 3. The rechargeable battery power supply system is selected, which is suitable for field work without ignition, charge and discharge. 4. The relative path search of cable (which can be clearly in the middle of 30cm), buried depth detection and accurate positioning of common fault points are carried out in the same step with high efficiency. 5. Clarify the common fault points, and the instruments and equipment have visual display information without wave type analysis. ⒍ it will not be harmed by underground conditions (such as bifurcation of cable, bundling, distortion of connector, etc.). Like detecting bombs, it searches common fault points point by point, and the accurate positioning deviation is within more than ten centimeters, which is very accurate. ⒎ it will not be harmed by ground conditions, such as floor tiles, road greening, concrete ground, etc. 8. Check the safety on the spot, there is no risk to the inspector, and there is no secondary damage to the cable. ⒐ high quality and low price are acceptable to ordinary customers. We know that the insulation layer of cable is relatively low. In addition, the electric flow is very large in the whole process of operation, and there are significant characteristics after common faults. The actual classification is as follows: the first kind of common faults: a piece of cable is burned out or a phase is burned out. This kind of common faults lead to the posture of current relay on the distribution box, and the cable is seriously damaged at the common faults. The second type of common fault: short circuit fault of each phase of the cable. Similarly, this type of common fault causes the current relay and voltage relay on the distribution box to be in a bad position, and the cable is also seriously damaged at the common fault point (possibly caused by external force). The third type of common faults: the cable can only be short circuited in one phase, the current relay posture, and the common fault points are slightly damaged but significantly exposed. It may be due to the high voltage of this phase or the quality of the cable. The fourth type of common fault: internal short circuit fault of cable, no mark can be seen on the surface. This kind of common fault is generally caused by the quality of cable, which is relatively rare. Common faults of hn-213x cable can be easily detected by the fusion application of rangefinder and detector in mobile phone positioning system. In addition, the characteristics of different common faults and the length of cable can also be detected separately. The actual situation is as follows: the first type of common faults and the second type of common faults. If the cable is short (less than 500m), the common fault detector can be used to accurately locate the common faults immediately without the cooperation of the distance finder. The common fault points can be identified by stepping in the hand receiver along the relative path (the relative path can be measured while walking). The third type of common fault: because the cable is slightly damaged at the common fault point, the data signal sent by the transmitter leaks less here. When accurately locating the common fault with the detector, the marking scope is narrow. At this time, the distance between the common fault points can be measured with the distance meter, and then the accurate positioning with the detector is also very convenient. The fourth type of common fault: this type of common fault is the most difficult to predict among all cable faults at this stage. At this time, you can use a rangefinder to detect the cable on both sides of the cable, and then compare the detection results with the specific length, so that the common fault point can be defined in a small range (1-3m). At this time, dig the cable and find the problem, Or decisively cut off this section of cable (because the cable is very cheap, the insulation layer is low, and the connector is easy to do), or use a detector to select the audio frequency for accurate positioning in this section, which can also identify the common fault points. At this stage, the cable fault detector based on impulse flashover method, which is applied by many customers of cable fault detector in power engineering, generally can use a distance meter to roughly measure the distance between common fault points when dealing with common faults of low resistance of cable and common faults of dead grounding device (the distance detection of such common fault points does not need high-voltage charging and discharging machinery and equipment, and the bottom pressure single pulse method is used) However, ignition, charging and discharging and listening to sound are still used for accurate positioning of common fault points. In addition, the relative Pathfinder of such instruments and equipment is separated from the designated instrument, which makes it impossible to specify the relative path at the same time when selecting the correct relative path, and usually deviates from the relative path when specifying. Moreover, due to the limitation of the basic principle, the relative Pathfinder of such instruments and equipment finds the relative path of the cable It is impossible to find the exact relative path of the cable when the cable is in the middle of the total width of 1-2m. Considering the applicability, hn-213x cable fault detector just fills the shortcomings of the application. It can accurately locate the common fault points of the cable, detect the buried depth and the relative path smoothly. The instruments and equipment are very vivid in the marking of common faults, relative path and buried depth No need to do technical index analysis or rely on the working experience of the operator. It makes the original complex fault test work become a relaxed and interesting thing. Therefore, many customers of impulse lightning cable tester can form a set of extreme low-voltage cable fault tester if they have another DW cable fault detector and the original distance finder. In addition, the The common faults of low resistance and short circuit of external high-voltage cable can also be specified quickly to improve the efficiency many times.
