g650 Generator Protection & Control System Use the G650 for the detection of the loss of excitation of synchronous generators, and to automatically remove the generator from service. Loss of excitation can be damaging to the machine, and/or detrimental to the operation of the system. It is recommended that loss-of-excitation protection be considered for all synchronous generators. Protective relays are applied as backup protection for excitation systems, which in most cases include minimum-excitation limiters to prevent under-excitation. An offset mho characteristic was chosen to provide...
