A CT Current transformer) is used to reduce the high current on primary for measuring it with small range instruments. So its number of turns on secondary will be high. So if we open circuit the secondary it will results in very high voltage on secondary which in turn damage the CT.

how to calculate voltage drop and followed by cable calculation?is there avail in formula?
