Abstract

The generators are the most expensive pieces of equipment in the a.c. power system (see fig. 1.7) and are subject to more possible types of trouble than any other equipment. The desire to protect against all these abnormal conditions and yet to keep the protection simple and reliable has resulted in considerable divergence of opinion on the choice of protection.
