An Introduction to Electrical Safety: Substations and Switchgears

COURSE NO: E02-017
An Introduction to Electrical Safety: Substations and Switchgears
Course Highlights

This online engineering PDH course provides an introduction to electrical safety when working around electric power distribution substations and switchgear. For the purposes of this discussion, a substation refers to substations and switching stations.


A substation provides a protected area for switching power circuits and may include transforming power from one voltage to another. A substation presents an inherent safety hazard because usually only some portions of the substation apparatus can be deenergized for maintenance. For safe operation and maintenance, a thorough knowledge of the substation, including aerial and underground line connections, is necessary.


This 2 PDH online course is intended for electrical engineers and electrical maintenance technicians interested in acquiring knowledge about safe working procedures around electrical substations and switchgears.
