Vlf Cable Testing Equipment

Advanced test equipment rentals offers vlf hipot and cable testers from top brands like high voltage baur hv diagnostics and more.

Vlf cable testing equipment. As higher voltage vlf equipment is developed standards may be adapted to increase the voltage level for application. Vlf testing of cables is supported in iec 60502 up to 35 kv and in ieee 400 2 up to 69 kv. Vlf high voltage test equipment of the hva series by b2 electronics is the most advanced vlf ac dc hipot test equipment of its kind available. Hva30 5 high voltage tester.

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.

This combination of size and power makes very low frequency cable testing perfect for testing longer sections of cable and apparatus. Vlf testers are smaller and more practical than ac testers but output the same amount of power as a 50 hz mains device. During the test cables are subjected to a test voltage significantly higher than what they experience during normal operating conditions. The vlf test can be used in a number of ways.

Vlf testing uses very low frequencies as part of an ac cable maintenance routine. This equipment negates the need for on site generation large step down transformers or generating company supplies to be employed to power the items under test.
