excitation loss protection relay / for generators
CEH GE Digital Energy



  • Measured/monitored value:

    excitation loss

  • Other characteristics:

    for generators


The CEH relays are utilized to discover and detect the loss of excitation among the synchronous generators and to detach the generator automatically from the service as well. This certain loss of excitation can wound the engines and can also be destructive to the performance of the system. The security and protection against loss of excitation is very much advised and should be taken into consideration for securing all synchronous generators. It has an impedance unit and loss of excitation protection and control features.
