high voltage test of power cables
high voltage test of power cables
(OP)
why in the power frequency tests of HV power cables the two ends of cable on the reel are immersed in water ?and what conditions this water should have?
thanx

RE: high voltage test of power cables
Is it possible the test description is reversed? As a production test, it would make more sense that the reel would be water immersed except for the ends. IEEE Std 400 makes no mention of water for a field test, but typical ‘tap’ water is probably conductive enough not to need any additional treatment.
RE: high voltage test of power cables
The termination uses clean water and the water is usually pumped through the termination to eliminate heating.
Go to the haefely site with the following link, it gives a good description of how they work etc.
