WebNov 10, 2005 · Re: High Resistance Grounding Device type "59" is an overvoltage detection relay. Device type "59G" detects an overvoltage condition in the ground wire. I infer that this device senses a ground fault from the fact that current flowing in the ground wire will create a larger than normal voltage. I do not know what that "pulsing contactor" might be.
