Occupation
Substation technician
Substation technicians install, test, and maintain the transformers, breakers, switchgear, and protection relays that step voltage up and down across the grid. The work happens around high-voltage equipment, so isolation, grounding, and permit discipline matter as much as technical skill. Fault call-outs can mean working outdoors in poor weather at unsociable hours.
Also known as: Substation electrician · Substation maintainer · Power system electrician
