Application of High Voltage DC Power Supply in Cable Fault Test
The power cable fault tester is composed of three main parts: the main unit of the power cable fault tester, the cable fault locator, and the cable path meter. The host of the cable fault tester is used to measure the nature of the cable fault, the total length and the approximate position of the cable fault point from the test end. The cable fault fixed point instrument determines the precise location of the cable fault point based on the approximate location of the cable fault point determined by the host computer of the cable fault tester. For buried cables with unknown orientation, a pathfinder is required to determine the underground orientation of the cable. The basic method of testing power cable faults is to apply high-voltage pulses to the faulty power cable to generate breakdown at the fault point of the cable. When the breakdown point of the cable fault is discharged, electromagnetic waves are generated externally and sound is emitted at the same time. The cable fault test signal generator has 3 levels of high-voltage output: 0~32 kV, 0~16 kV, 0~8 kV, mainly used for distance measurement and fixed point of high resistance and flashover faults of medium and low voltage power cables, and can also be used Used as a DC and pulse voltage source.
