01 · The overview

What is a Substation Technician?

Substation technicians are responsible for the maintenance, repair, and operation of electrical substations. They inspect equipment, perform diagnostic tests, and troubleshoot issues to ensure the reliable delivery of electricity. They work with high-voltage equipment and must adhere to strict safety protocols.

A substation technician starts by inspecting relays, breakers, insulators, and wiring diagrams, then uses ohmmeters, voltmeters, and ammeters to test equipment and circuits. You record test results, analyze data to diagnose malfunctions, and perform repairs such as replacing brushes or refilling transformer oil. Much of the day is targeted testing, careful isolation of defective relays via switches, team coordination, and accurate documentation that supports future troubleshooting and safe operations.
