Day in the life
A Day in the Life of a Substation Technician
What substation technicians actually do from the start of a shift to the end: the tasks, tools, schedule and realities of the job.
Hold a tailboard briefing at the substation. From there, the day usually includes test and maintain transformers and breakers, calibrate and test protective relays, and troubleshoot control and communication systems. Most work full-time days with on-call duty and storm work.
