Energy Efficient Harmonic Mitigating Transformers

HPS Centurion®  Series

HPS provides two lines of energy efficient harmonic mitigating transformers:

HPS Centurion®

The HPS Centurion® energy efficient, harmonic mitigating transformer with zero sequence flux cancellation technology is specifically designed to treat the harmonics generated by computer equipment and other non-linear, power electronic loads.  Combining zero sequence flux cancellation with phase shifting treats 3rd, 5th, 7th, 9th, 15th, 17th and 19th, harmonics within its secondary windings. 

Typical applications of severe non-linear loading conditions include data centers, internet-service providers, telecom sites, call centers, broadcast centers, etc.
