The operation of a generator may be as easily affected by faults within the machine itself as by external disturbances occurring on the network to which it is connected. The generator protection must therefore be designed to react efficiently in both conditions. All the various generator protection functions can be provided by the discreet relays. However, a much more cost-effective method is to use a multi-function protection relay, which performs all the functions in one relay. The GMS 7001 performs all the protection functions needed.
