Substation Technician

Also known as: Substation Electrician, Relay and Protection Technician, Substation Maintenance Technician, Power Systems Technician

AI Impact Score

20/100

Substation technicians maintain the critical high-voltage infrastructure that connects power generation to the distribution grid. The complexity, safety requirements, and specialised knowledge of substation work provide strong insulation against automation. AI is entering through condition monitoring and digital relay testing tools, enhancing rather than threatening skilled technicians.
