Power Generation, Transmission, and Distribution

WTT 240

Course Description

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)

Outcomes and Objectives

Explain the generation of electrical power with a wind turbine generator from the local transmission system to a substation where a customer will purchase the generated power.

Objectives:

  • Explain all aspects of working with components of a high voltage transmission system.
  • Explain basic electricity, related math, and transformer theory with hands-on experience with single-phase transformers and various three-phase transformer banks.
  • Introduce transformer over-voltage and over-current protection, equipment grounding, cutout and lightning arrestor use and installation, current and potential transformer applications, use of the VOM, and principles of troubleshooting.
  • Demonstrate an understanding of substations, capacitors, voltage regulators, auto-boosters; practical experience in substation grounding, inspections, substation maintenance; operation and installation of high side fuses, power transformers, substation buswork, and transfer switches; methods of voltage regulation; and Supervisory Control and Data Acquisition (SCADA).
