I seem to have problems figuring out when shorting pins need to be in place on shorting blocks fed by CTs. One site needs pins on the unused leads, another site doesn't. reasons given for needing them is that when the current flows, it will seek a ground. If the shorting pin is not in place, it will still try to seek that ground connection, jumping over if necessary.

These are for high voltage cts, ones reading 69Kv.

Anyone have info to help me?

TIA
