Vlf Cable Testing Equipment

Vlf testing of cables is supported in iec 60502 up to 35 kv and in ieee 400 2 up to 69 kv.

Vlf cable testing equipment.

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. Vlf testers are smaller and more practical than ac testers but output the same amount of power as a 50 hz mains device. 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. Vlf testing uses very low frequencies as part of an ac cable maintenance routine.

Vlf cable testers support iec 60502 and ieee 400 2. Hva30 5 high voltage tester. 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.

This combination of size and power makes very low frequency cable testing perfect for testing longer sections of cable and apparatus. As higher voltage vlf equipment is developed standards may be adapted to increase the voltage level for application. Its most frequently used to ac field test medium and high voltage cables and test rotating machinery like motor and generator coils. Hva28td vlf high voltage test set.
