Take a look at some of our problem-solving discussions – If I had transformer YNd11 and want to connect differential Protection is the CT on Primary should connect in Delta and CT on Secondary should connect in Star when I use Numerical relay or not?– Don’t need to reverse the connection of CT?– No need

Join our protection relay WhatsApp groups – Does the CT ratio setting in the relay already correct? Does secondary CT connect properly?– The amperes showing at analog meter are correct.– Your relay reading is not correct, and your Ip shall be the same as I>. Make sure that I am in the secondary setting– How
