The reactor products available from HPS include three phase line reactors (RM Series), three phase DV/DT filters (RC Series) and a wide range of custom and specialty reactor products as well. We take pride in our ability to manufacture, on a timely basis, custom designed and built reactors for almost any application.

600V Class Dry-Type Distribution Transformers
HPS offers one of the broadest ranges of dry-type distribution transformers available in North America. This includes single and three phase general purpose transformers, non-linear (K-factor) transformers, energy efficient (TP1) transformers, low temperature rise transformers, low voltage lighting transformers, encapsulated transformers and three phase drive isolation and autotransformers. Available in standard ratings from 9kVA to 750kVA in many voltages, each of these products is also available in custom ratings and voltages.

Motor Starting Autotransformers
HPS's motor starting autotransformers have been an industry standard for many years. Our 2909 and 3009 series product lines are designed for medium duty service and are manufactured in accordance with NEMA standards. We offer both three phase two coil and three coil units available in ratings from 25HP to 1600HP.

Power Quality Products
Not everyone has the same power problem. Finding the most cost-effective solution requires some analysis of your equipment, the power system and the available solutions in the market. HPS offers a wide range of Power Quality Products to solve your power problems. These include voltage regulators, line voltage conditioners, single phase and three phase super isolation transformers and Harmonic Mitigating Transformers.

Dry-Type Power Transformers
Hammond Power Solutions produces a wide range of standard three phase dry-type power transformers. However, this is just some of our capabilities. We also manufacture unit substation transformers and traction duty rectifiers, and cycloconverters can be offered for a variety of environmental conditions and built to meet the most onerous duty, including MIL standards. In addition to conventional indoor applications, our dry units are located outdoors, on drilling platforms, in network vaults and in every location where airborne contaminants pose a risk to electrical equipment. When selecting HPS, you will never be limited. Our specials capability includes ratings up to 25MVA and 46kV. We can build customized products for you affordably while still maintaining our short lead-time capabilities, for almost any application.
