Hello friends,
I would like to receive some feedback from you related to how to size the zero sequence CT for a Micom P211 relay.
In this case, there are no CT's in each one of the phases and we will use an external "window CT" to sense zero sequence current and in that way providing a 51G protection.
Our I0 is around 700 A.
I thank you in advance!
