MV solid state relay setting - guide?

[anbm]

Does anyone know any guides how to set the MV solid state relay?
Especially 50N,51N (neutral instantaneous and overcurrent). Thanks.

You mean how to input the settings or how to determine the settings? They should be determined from a coordination study, when you use a basic guide for settings the end result is often what happened at the superbowl.

LOL, nice!

This is a good reference for theory

Sorry...setting relay input (long time delay, instantaneous, etc) to archive the coordination study...

What model?

What model?

SEL

SEL

We will need a lot more information. I'm guessing that SEL has a thousand different relays, and a couple hundred that might be able to do MV overcurrent protection.

This is a pretty broad subject. I have been doing it for only 40 years and still am baffled at times. I'm only saying that to emphasize the scope of the question you are asking.
