The nameplate of the current transformer is based on the condition that the primary
conductor will be passed once through the transformer opening. The rating can be reduced
in even multiples by looping this conductor two or more times through the opening. A
transformer having a rating of 200 to 5 amperes will be changed to 50 to 5 amperes if four
loops or turns are made with the primary cable as illustrated.
