High Power Lab
Powertech’s High Power Laboratory offers evaluation, verification, and certification testing of medium- and high-voltage products to support manufacturers, power utilities, and other users of electrical equipment.
Areas of Focus
The lab is the largest grid-connected short-circuit testing facility in North America and operates independently of utilities and manufacturers. It has controlled power level capabilities for short-duration single-phase tests up to 400 MVA and three-phase tests up to 1,000 MVA.
Test services include load- and fault-interrupting tests, arc-resistance tests, momentary and short-time current tests, and failure-mode and exploratory tests involving applying precisely controlled distribution-level 60 Hz voltage and current to test objects.
All our certification testing, equipment development testing, quality assurance testing, and non-standard testing is performed in accordance with IEEE, ANSI, IEC, UL, and CSA standards.
