The VLF Tester kit is widely used in large generators, cables, power capacitor test AC voltage withstand test products.

Very low frequency (VLF) withstand testing is the application of an AC sinusoidal waveform, generally at 0.01 – 0.1 Hz, to assess the quality of electrical insulation in high capacitive loads, such as cables. During the test cables are subjected to a test voltage significantly higher than what they experience during normal operating conditions. The higher test voltage allows for weak points or pre-damaged areas within the cable to breakdown during the test, rather than while they are in service. Essentially, the VLF withstand test is a “go or no-go” test, otherwise known as a “pass/fail” test.
