Installs, tests, repairs and maintains generators, transformers, relays, regulators, switches, circuit breakers, recording instruments, control systems and other circuit elements. Works in high voltage (HV) electric vaults and substations, and on underground and overhead high voltage primary distribution systems.

Incumbent ensures that necessary materials, technical instructions and tools are available to accomplish the task. This HV electrician obtains required information or decisions from the supervisor on problems that come up during planning or performance of the work. Incumbent knows when to seek supervisor assistance in applying proper procedures, policies, written instructions and other directives in completing an assigned task.

Incumbent must have the ability to operate and maintain complex electrical systems ranging from 200 volts to 34,000 volts.

Dismantles, repairs and assembles asynchronous and induction motors, motor generators, protective relays, and high voltage circuit breakers. Cleans, adjusts, and repairs electrical equipment such as air circuit breakers and remotely controlled supervisory and telemeter equipment and installs rigid conduits. The high voltage electrician pulls in conductors, assembles bus bars, and phases out and connects conductors. This position troubleshoots distribution circuits and controlling equipment to locate and correct the causes of outages and improper operation.

The incumbent makes emergency cut-outs and substitutions of power lines and equipment, sometimes working on distribution systems when they are energized.

Incumbent performs a variety of tasks such as repairing electrical auxiliary equipment in the boiler and refrigeration plants:
