K-Rated Transformer

K-rated energy-efficient transformers are designed to tolerate heating generated by harmonics. They are rated for 600 volts and below and are designed and tested for applications that use non-linear loads. Harmonic effects can manifest in various ways, such as causing telephone interference, equipment vibration, breakers tripping, and device malfunctions.
