    GE Protection Setting Help

    hi, anybody with ge protection?
    I am questioning the signal source 2 setting. We are using source 2 for loss of excitation but the the source 2 setting has vt phase set at "none". will the loss of excitation function eventhough the setting of the source 2 vt phase is set at none?

    To be honest, I'm not sure! But the only way to find out would be to take the generator offline and test the relay with the as found settings. If its not possible to take the generator offline, acquire another relay and case, and upload the settings from the in service generator. Then you should be able to perform your relay testing to verify whether or not that function is working properly. If it isn't working on the "test" relay, then you can be certain it isn't working on the one in service.

    Also I am not sure of the relay. Are you referring to a G60?

    Sorry I can't give you a direct answer.
