K Factor K factor is a simple numerical rating that indicates the extra

heating caused by harmonics. A transformer’s ability to handle

the extra heating is determined by a K factor rating. A standard

transformer has a rating of K-1. A transformer might have a rating

of K-5, which would be an indication of the transformer’s ability

to handle 5 times the heating effects caused by harmonics than

a K-1 rated transformer.
