The HVA90 provides the testing and commissioning engineer with a versatile high voltage power source suitable for testing electrical plant including cables: XLPE, PE, EPR, PILC etc, Capacitors, Switch-gear,
[email protected]high power HVA90 Test System is capable of testing cables up to 3,300 m (1 μF at 0.1 Hz and 64 kV rms). The variable output frequency allows the testing of even much longer cables. At 10 μF – 0.01 Hz and 64 kV rms a length of approx 33,000 m can be tested (see technical data).

Get Price2005-8-30Oscillation breakdown takes place at Vb<64kV and VblOlkV that corresponds to cut-off frequencies 1816.5 and 1819MHz respectively. It means that the experimental frequency broadband is equal to 2.5MHz whereas from cold measurements with help of RF line we obtained frequency broadband 2.2MHz.
