Circulating ground current
WebSep 1, 2024 · This study describes an actual problem with circulating current at the ground grid of an actual power system that has an air‐core reactor. Such reactors generate a large amount of magnetic... 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
