What does current transformer (CT) polarity mean? This article is very clear

author:Electrical Design Teacher Di
Why is the current transformer called (CT), presumably many small whites are half-understood. Current transformer is called (CT). Current transformers are similar to transformers in that they are inductive devices, but unlike transformers, they scale down the current (down to 5A) for instrument measurement. So what exactly does the polarity of a current transformer (CT) mean? The following small series of detailed explanations to introduce to you, I hope to be of some use to everyone!
