Monday, June 6, 2011
Fremont, CA, June, 2011 – IEM, the largest independent full-line manufacturer of electrical and power quality equipment in the U.S., recently completed UL Listing of Open Delta PT (potential transformer) with various voltage ratios as an option to Vesta-AR switchgear. Until now, only YY PT was available with different voltage ratios. Open Delta PT would allow customers with ungrounded systems to effectively use open delta PT’s, increasing the reliability of PT’s in the event of a ground fault.
Both YY and Open Delta PT’s are available with a variety of standard voltage ratios and other custom voltage ratios if required. All PT’s are constructed to the highest quality and have an extended life required to meet the demands of critical facilities such as hospitals, data centers, and other industrial applications.
