WebVerifying ground paths. Before testing, the ground bus of the system should be verified to determine that unintended ground paths do not exist, which could bypass the ground fault equipment discussed in this document. This may be accomplished either by visual inspection, or with the assistance of high-voltage testers and resistance WebWhenever a ground fault detector indicates a ground fault, field technicians must assume that conductors or equipment are damaged and need repair. Unless extensive field testing shows that no fault exists, the only safe assumption is that damage has occurred and there is an existing electrical hazard to the system and repair is required. theta ag https://designchristelle.com
