CSA & UL Qualification as a Test Facility

Power Quality International’s Medium and Low Voltage Class, Dry-Type and Cast-Coil Transformers have been ‘shake table’ tested for seismic withstand capability. These steps were undertaken in an effort to better serve the needs of the US Department of Defense, and our clients in California and other locations in North America where OSHPD Seismic Pre-Certification is required for transformers and other power distribution devices. It gives us great pleasure to announce that we have received Seismic Pre-Certification for all of our Medium and Low Voltage Class, Dry Type and Cast-Coil Transformers.

The sample selection and test criteria were planned 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). As previously mentioned, OSHPD has a program to ‘pre-certify’ devices, based on actual shake table testing.

As required by the aforementioned codes, PQI transformers demonstrated their ability to function after the seismic tests.
