Thanks for replies. I was told on another forum that some current is going thru the CT and can be found by taking the voltage of the CT circuit that is across the CT and looking up what the excitation current is on a CT data sheet, that graphs secondary excitation current to secondary voltage. I...
I have noticed in the field two ways of injecting CT secondary test current, when testing the integrity of the entire CT circuit that is connected to a CT, once all the burden elements have been individually tested. One way is to break away the leads at the CT terminal board and connect them to...
