Summary

An instrument is described for detection of electrical grounding of the 3.6 megawatt dc test loop in the Heat Transfer Laboratory of the Savannah River Laboratory. The dc loop is ungrounded except for leakage through cooling water in the buses and loads. A high-frequency, low-voltage signal is applied to the positive dc bus. A tuned amplifier receives the signal from the negative bus. Loss of the received signal indicates a ground at either bus or at the load. Alarm and shutdown circuits are actuated whenever a ground occurs.
