Capacitance test
Capacitance test
(OP)
A senior engineer mentioned a capacitance test as a means of locating a fault on a 33Kv underground cable. Can someone enlighten me as to what is involved in such a procedure?

Only problem is, that is only accurate to about 10 per cent, which can be quite a distance.
To get really close, use a TDR.

Thanks, that was the point. The cable was shorted to earth. The fault was found in no time by pulse echo but I was interested to know about the capacitance test and if it is still used. Thanks all for info.
