Circulating ground current
WebDec 5, 2024 · Ground Fault A common characteristic of all three solidly-grounded system shown here, and of solidly-grounded systems in general, is that a short-circuit to ground will cause a large amount of short-circuit … Websource, it provides lower ground fault current than with multiple point grounding. Also, relay coordination is simple since there is no variation in ground current. In addition, third-harmonic circulating currents are eliminated. The principle disadvantage of single point grounding is that if the grounded power source is out of service, the
