WebGround relays for these systems require high relay sensitivity because the fault current is very low compared to solidly grounded systems. Most ground-fault detection methods use fundamental-frequency voltage and current components. The varmetric method [2] is the traditional ground fault detection solution in ungrounded systems. WebHistorically, the method of system grounding selected for various electrical system settings, e.g., industrial, commercial, etc., dates back to the early part of this century when only two ...

Webgrounded as provided in this article when the voltage to ground does not exceed 300 volts. Higher voltage systems may be grounded. It is also recommended that ungrounded systems supplying industrial equipment and operating at more than 150 volts and less than 600 volts be equipped with ground detectors. 250-6. Furnace Circuits.
