Abstract
In some aspects, a ground detection system may measure a difference from a tie point of the ungrounded electrical system and a ground point to determine if a grounded condition exists. The ground detection system may measure a plurality of signals at a plurality of distributed overload protection devices. The ground detection system may compare the plurality of signals from each of the plurality of distributed overload protection devices to stored threshold values. The ground detection system may determine a location of the grounded condition based at least in part on the comparing the plurality of signals from each of the plurality of distributed overload protection devices to the stored threshold values. In various embodiments, the location can be based on a length and an impedance of electrical circuit wiring. The ground detection system may display the location of the grounded condition on a display. Numerous other aspects are described.
