【国外标准】 IEEE Guide for Generator Ground Protection

The guide is intended to assist protection engineers in applying relays and relaying schemes for protection against stator ground faults on various generator grounding schemes. The existing guide is out-dated due to rapid technology development. Hence, the revised guide includes new stator-ground-protection principles that have evolved with the use of new technologies in relay designs. Additional application examples are included, and other issues raised by the users are also addressed. The… read more guide is not intended for the selection of generator or ground connection schemes. The recommendations made pertain to typical generator installations. However, sufficient background information relating to protection requirements, applications, and setting philosophy is given to enable the reader to evaluate the need to select and apply suitable protection for most situations. read less
