Power Generation, Transmission, and DistributionWTT 240
Prerequisite: ET 120 with a grade of "C" or better. Identifies and explains the regulatory requirements as well as the risks and hazards associated with working on high voltage systems. Applies three-phase electrical power generation characteristics to utility scale transformers, relays, capacitors, switchgear, and related components for both common Delta and Wye configurations. (30-0)
