Harmonic mitigating transformers
curb harmonic currents that K—factor transformers do not, reduce transformer heating caused by harmonics and improve upstream power quality, all while maintaining the NEMA TP—1 standard for energy efficiency. The transformers accomplish harmonic mitigation by providing good source impedance and sine wave phase shifting. One of three models is selected based on the type of building or installation.
