Hipot Test Equipment Vlf Cable High Voltage Tester
Hipot Test Equipment Vlf Cable High Voltage Tester is a type of electrical testing equipment used to test and locate underground cables and faults in power distribution systems. The VLF tester generates a low-frequency AC voltage, typically between 0.1 Hz and 0.01 Hz, which is applied to the cable or system being tested. The VLF tester is able to detect cable insulation defects, such as cracks or voids, and can also be used to locate cable faults by measuring the time delay of the reflected signal. VLF testing is a non-destructive method and is commonly used in the power industry to help ensure the reliable operation of power distribution systems.
