Grounding of Industrial Low-Voltage Power System
Michio Kikuchi · IEEJ Transactions on Power and Energy · 1991
Author show that in the low-voltage power system, the grounding electrode resistance (Re) and the system grounding resistance (RN) are ruled by concerned power system bank capacity P(kVA). So by reasons of safety, protection and economy, it leads the following formula P(Re+RN)=const. Still more, he studies that super low resistance type (Re=under 25Ω) gives an optimum solution for industrial low voltage power sytem by means of theories and examples.More, it is effective to suppressing of surges and noises concerning to power system etc. Author show it by some reports and experiences.And author analyze the universal suitable ability for grounding standard of main countries in recent subject.
