Assessing the Condition of Aging Electrical Equipment

This course discusses the wide variety of materials used to fabricate electrical equipment; limiting factors, such as temperature or water content for various materials; and testing that can be performed to evaluate the condition and remaining life of electrical components. When the condition of various components is evaluated, and limiting conditions are understood and monitored, electrical equipment can be rtilized for much longer.

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.

Learn to identify electric equipment aging mechanisms. Compare periodic testing to periodic replacement and be able to estimate the remaining service life of electrical components.

This course can be applied to the Electrical Engineering Certificate.
