Vlf cable testing equipment.

Vlf testers are smaller and more practical than ac testers but output the same amount of power as a 50 hz mains device. Its most frequently used to ac field test medium and high voltage cables and test rotating machinery like motor and generator coils. As higher voltage vlf equipment is developed standards may be adapted to increase the voltage level for application. Hva28td vlf high voltage test set.

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. 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. During the test cables are subjected to a test voltage significantly higher than what they experience during normal operating conditions.

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 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. Vlf testing uses very low frequencies as part of an ac cable maintenance routine. The vlf test can be used in a number of ways.
