Description
The Suitcase Impulse Generator is designed to locate faults in power cable by the high-voltage impulse method, in which an impulse is transmitted down the cable to cause the fault to arc. The arcing fault is then pinpointed using an appropriate impulse detector. The instrument can also be used to perform modified proof tests. The Suitcase Impulse Generator is a compact, 41-lb (18.5kg), unit that impulses at 3, 6, 9, 12 or 15 kV (chosen by a selector switch). Its size, 8.5 H x 14.5 D x 17.5 W in. (216 H x 368 D x 445 W m), makes it easy to carry long distances or into tight locations.

- Unlike conventional impulse generators, the Megger Suitcase Impulse Generator incorporates a solid-state circuit generating an impulse that is transmitted to the cable by a pulse transformer. This approach produces noiseless operation because it avoids the use of a mechanical switch or spark gap to produce the impulse.
