what is k factor in isolation transformer?

The K factor in an isolation transformer refers to a rating that indicates the transformer’s ability to handle non-linear loads without overheating. It is particularly important for applications involving electronic equipment that generates harmonic currents. The K factor helps in selecting the appropriate transformer size by accounting for the additional heating effects caused by these harmonics. A higher K factor indicates greater tolerance for harmonic distortion, ensuring reliable operation and longevity of the transformer.
