Manufacturer
Power Quality International
Transformers built for harmonic-heavy loads
Power Quality International builds dry-type transformers for facilities where the load is anything but linear. Its harmonic mitigating and ultra-efficient ranges are designed for the distortion that variable-speed drives, switch-mode supplies and LED lighting put back onto a distribution system.
What we carry
- Harmonic mitigating transformers
- Ultra-efficient transformers (CSL3, CSL3 Plus, CSL4)
- Medium voltage power transformers
- General purpose transformers
- Three phase to single phase converters

The relationship
Access and Power Quality International
Access represents PQI nationwide, from our base in Northeast Wisconsin. Transformer selection is where a lot of avoidable heat and loss gets designed into a building, so we size these against the actual harmonic profile rather than the nameplate load.
Transformers
Dry-type transformers specified against the harmonic profile of the real load, not the nameplate.
Let’s talk about what can’t go down.
