Generator and Transformer V/Hz Capability - standard curve? 2

[Truant]

Hello Everyone,

I am working on confirming some generator and transformer protection coordination and I am having trouble finding manufacturer "V/Hz capability" curves for some of our older equipment.

Do any of you know if there is an industry standard for building a standard type curve?

I have looked through IEEE searching for 'V/Hz' and 'over-fluxing' capability, but haven't found anything.

Thanks for the help!


EDIT: I found plenty of protection setting recommendations (eg. in "C37.102 IEEE Guide for AC Generator Protection", but the NERC standard says specifically to coordinate with generator and transformer V/Hz capability. Which I don't have.

Hi prc,

Turbines and generators. If I recall corrrectly, generator manufacture was centred around Pittsburgh, but all our contact into the group was via Orlando.

I'm fairly certain the ABB contact for Westinghouse transformers is:
