Electrical Infrastructure A: Electrical Substation Equipment Aging

Get acquainted with aging mechanisms and the aging considerations for components found in substations. As craftsmen, engineers, supervisors and managers who are responsible for performing, supervising and scheduling maintenance activities, being proactive is vital.

Take this course along with the half-day booster courses Electrical Infrastructure B and Electrical Infrastructure C to complete 28 PDHs in just one week. Also, enroll in our online Engineering Ethics course for two additional PDHs to complete the required 30 PDHs for PE license renewal.

This course can be applied to the Electrical Engineering Certificate.

Who Should Attend

This course is intended for craftsmen, engineers, supervisors and managers who are responsible for performing, supervising and scheduling maintenance activities; determining periodic maintenance needs; or determining end-of-life for substation components.

Benefits and Learning Outcomes

  • Identify recognized failure modes and aging indicators
  • Gain insight into periodic and in-service testing
