Tom Divine, PE on Switchgears and Transformers

Tom Divine, PE, Senior Electrical Engineer for Johnston shares part of an article he wrote that originally appeared in Consulting-Specifying Engineer magazine in July 2020.

“Switchgear, transformers and uninterruptible power supplies are among the largest, costliest and most critical devices in a facility.

A transformer is an alternating current elecromagnetic device that magnetically moves power from one or more primary circuits to one or more secondary circuits.”
