Surge voltage generators are used for pre-locating as well as for pin-pointing of high and low resistance faults in power cables. The stored energy of the high voltage capacitors is fed at intervals into the faulty cable. This causes an acoustic noise at the fault position which can be detected with a ground microphone and an audio frequency receiver.
The SSG 500 is a portable surge voltage generator in a sturdy 19" steel housing. The output voltage is selectable in 3 ranges, 4 / 8 / 16 kV. Maximum safety is guaranteed by a safety interlock circuit, automatic discharging device, enclosed housing and separation between operation and protection ground. The high voltage is measured in 3 ranges on a kV-meter.
