Wuhan UHV's Cable Fault Location Detector can help many power workers more convenient for all kinds of power testing.

The method of finding cable fault points is an important part of power system maintenance and fault repair. The following will address the method of finding cable fault points to answer, and give the corresponding cases and solutions.

Question 1: What is the cable fault finding methods?

Answer: Cable fault finding methods include direct measurement and indirect measurement. Direct measurement method is to determine the location of the fault point by measuring the cable resistance, inductance and capacitance and other parameters. Indirect measurement method is through the measurement of cable voltage, current and power parameters to infer the location of the fault point.

Case: A power company uses the direct measurement method to find the fault point when performing cable fault detection. They use a cable fault tester to measure the resistance value of the cable and determine the fault point location based on the measurement results.

Solution: To solve the cable fault problem, you first need to use a cable fault tester for detection. According to the detection results, choose the appropriate finding method, such as direct measurement method or indirect measurement method. According to the measurement results, determine the location of the fault point and take appropriate repair measures, such as replacing damaged cable segments and repairing joints.

Question 2: How to use the cable fault tester for direct measurement method?

Answer: When using the cable fault tester for direct measurement method, you need to measure the resistance value of the cable. First, connect the test probe of the tester to the cable near the fault point, and then measure the resistance value of the cable. According to the measurement results, the location of the fault point can be determined.

Case: A power company uses a cable fault tester for the direct measurement method when performing cable fault detection. They measured the resistance value of the cable and determined the fault point location based on the measurement results.

Solution: To solve a cable fault problem, you first need to use a cable fault tester to perform the direct measurement method. According to the instructions of the tester, the resistance value of the cable is measured and the location of the fault point is determined based on the measurement results.

Question 3: How to use the cable fault tester for indirect measurement method?

Answer: When using the cable fault tester for indirect measurement method, you need to measure the cable voltage, current and power and other parameters. First, connect the test probe of the tester to the cable near the fault point, and then measure the cable voltage, current and power and other parameters. According to the measurement results, the location of the fault point can be inferred.

Case: A power company uses cable fault tester for indirect measurement method when performing cable fault detection. They measured parameters such as voltage, current and power of the cable and inferred the fault point location based on the measurement results.

Solution: To solve the cable fault problem, you first need to use a cable fault tester for the indirect measurement method. According to the instructions of the tester, measure the cable voltage, current and power and other parameters, and infer the fault point location according to the measurement results.

Summarize: the methods to find the cable fault point include the direct measurement method and the indirect measurement method. The direct measurement method is to determine the location of the fault point by measuring the resistance value of the cable, while the indirect measurement method is to infer the location of the fault point by measuring parameters such as voltage, current and power of the cable. A cable fault tester is used to detect and determine the location of the fault point based on the measurement results, and then appropriate repair measures are taken, such as replacing damaged cable segments and repairing connectors.
