Did the DOE 2016 and NRCan 2019 efficiency regulations result in product brand changes for HPS?

The obsolete HPS TP1/C802.2 rated Sentinel, Synergy, Centurion and Express lines were still available in the Canadian until the NRCan 2019 efficiency levels (same as DOE 2016) were mandated. In addition, the older medium voltage Millennium line was still available in Canada until NRCan 2019 May 1st, 2019.

The older lines were replaced with DOE 2016 and NRCan 2019 compliant low voltage general purpose distribution transformers (formerly Sentinel G), K-factor rated distribution transformers (formerly Sentinel K), harmonic mitigation transformers (formerly Sentinel H), general purpose commercial transformers (formerly Express G) and the energy efficient drive isolation transformers (formerly Tribune E) (Canada only) product lines. In addition, the medium voltage VPI transformers (formerly Millennium G and Millennium E) and medium voltage cast resin transformers (formerly EnduraCoil E) lines also meet the updated DOE 2016 and NRCan 2019 efficiency levels. While exempt from regulations, the encapsulated transformers (formerly Titan N) often meet or exceed the DOE 2016 and NRCan 2019 regulations.
