Great info. I have a question. If external ct ratio is 180/1 and external pt ratio is 22000/110, meter ct ratio is -/5 and pt ratio is -/110. Is it possible to have such connection? If yes, then what will be the multiplying factor in that case and if no, please share the reason why?
@@relayprotectionelectrical thanks for replying 🙏 How much difference in reading should we expect? At present we are using such set up in one of our feeders and taking readings on that basis. As you’re saying there will be accuracy issues, is there a way to evaluate how much difference in readings are we talking about? In the above case we are using MF as 36000

Accuracy problem will be there as meter CT is 5 A and you are going to connect meter from CT secondary of 1 A.
