What should V/Hz protection trip?
What should V/Hz protection trip?
(OP)
Should the V/Hz function in a generator protection relay trip the GCB, FCB, master fuel and turbine or only the GCB and FCB? I have an application where only the GCB and FCB are tripped but another where it hits all 4. Both are for 660MW units.
Thanks.
Thanks.
