Vlf Cable Testing Equipment

Its most frequently used to ac field test medium and high voltage cables and test rotating machinery like motor and generator coils.

Vlf cable testing equipment.

Hva30 5 high voltage tester. During the test cables are subjected to a test voltage significantly higher than what they experience during normal operating conditions. Vlf cable testers support iec 60502 and ieee 400 2. 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.

Advanced test equipment rentals offers vlf hipot and cable testers from top brands like high voltage baur hv diagnostics and more. 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. Hva68 2 cable tester new hva90.

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. Hva40 5 hipot tester new hva45td vlf high voltage test set new hva60 ac hipot. The small size and high power of the vlf tester helps to solve the practical problem of transmission loss during an ac test on very long sections of cable and apparatus in the field. 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.

This combination of size and power makes very low frequency cable testing perfect for testing longer sections of cable and apparatus. Vlf testing uses very low frequencies as part of an ac cable maintenance routine.
