PQI clients and customers benefit from over fifty years of engineering and technical hands-on field experience. With the exception of Antarctica, we’ve completed major assignments on every continent.
With its technical and manufacturing ‘know how’, PQI was first to develop and commercialize a number of leading-edge power magnetic technologies and products. These accomplishments, some of which are listed here, provide cost-effective solutions to various technical, power quality and energy efficiency problems.
2015 – First to offer three Transformer Efficiencies that Exceed DOE 2016 efficiency requirements, under the linear or nonlinear load environments for which they were designed.
First to receive a UL Certificate of Compliance per UL1562 for our Harmonic Mitigating, Medium Voltage, Cast-Coil Power Transformers. Both CSA and UL have approved our manufacturing facility as a Qualified Product Evaluation and Test Facility.
Measurements and test data generated during product evaluation is now accepted by both CSA and UL for product approval.
Power TransFilters™ have also received Seismic Pre-Certification in accordance with the requirements of the International Building Code 2012 (IBC2012), the California Building Code 2013 (CAB2013) and the National building Code of Canada 2010 (NBC2010). In addition, the transformers specifically met the requirements of OSHPD (Office of Statewide Health Planning and Development of California).
PQI’s Standard Z3 Efficiency Rating exceeds the US DOE 2016 requirements. Optional Z3+ and Z4 (US DOE CSL 4) efficiencies are available when their additional cost produced an attractive payback and ROI.
