Polarity: Figure 1 shows the internal construction of a current transformer. One face of the transformer is identified as H1 and the opposite face is identified as H2. The secondary leads are identified as X1 and X2. Current flowing out of terminal X1 will have the same polarity as current flowing into terminal H1.
