CEH Loss of Excitation Relay

CEH Loss of Excitation Relay

The type CEH relays are used 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.
