HPS Sentinel® H Energy Efficient Harmonic Mitigating distribution transformers are rated for 600 volts and below. Typical applications of severe non-linear loading conditions include data centers, internet-service providers, telecom sites, call centers, broadcast centers, etc.

Energy efficient harmonic mitigating transformers with zero sequence flux cancellation technology, are specifically designed to treat the harmonics generated by computer equipment and other non-linear, power electronic loads.

Superior to K-rated and conventional transformers in reducing voltage distortion and power losses due to current harmonics created by single-phase, non-linear loads such as computer equipment.

Combining zero sequence flux cancellation with phase shifting treats 3rd, 5th, 7th, 9th, 15th, 17th and 19th, harmonics within its secondary windings.
