Sensitive ground fault relays (GFRs) on high voltage underground electrical equipment have been in used for a number of years to improve mine safety. Advanced GFRs do more than just interrupt fault current flow. They can also reveal linkages as they develop so ground faults are detected before they become critical. 3 figs.
