What are the limitations of self-powered relays?
We are pushing a vendor of our 34.5kV switchgears to provide 3A pick-up on ground faults with a self-powered relay. The vendor says that he doesn't believe one exists. If that is true, what is the reason?
I'm new to the company and I'm not directly involved (at least not yet) with the issue but I want to understand it better. I have some basic knowledge of relays but obviously not to this degree (at least not yet).
