The NOC system is updated every 5 years to reflect changes in the labour market. Government forms and labour market data may group and refer to an occupation differently, depending on the system used.

Here is how this occupation has been classified over time.

Updated Mar 31, 2020

In general, power system electricians work in distinct areas: power generation, substation equipment, protection and control, and metering.

In power generation, power system electricians work with systems and equipment such as:

  • Generators
  • Wind turbines
  • Solar arrays
  • Biomass and associated equipment

In substation equipment, power system electricians work with high voltage equipment such as:

  • Circuit-breakers
  • Transformers
  • Switches
  • Switchgear

Their daily work involves adjusting relays, working on safety devices and general maintenance of large switch gear.

In protection and control power, system electricians work with a variety of equipment such as protective relaying and controls and Supervisory Control and Data Acquisition (SCADA) systems.

In metering, power system electricians work with a variety of recording devices such as:

  • Supervisory controls
  • Indicating and recording devices
  • Switchboards and equipment circuitry found in generating stations and powerhouses

This work includes the calibration and installation of metering equipment (meters). For example, they may install demand meters when a client company wishes to review the way it is billed for power usage. Based on data from demand meters, recommendations can be made to improve the company’s cost effectiveness.

Working Conditions
Updated Mar 31, 2020
  • Strength Required Lift over 20 kg

Power system electricians work both indoors and outdoors. The hazards of working with live electricity are reduced by the use of special equipment and training in safe work practices and procedures. They may find themselves working at heights or in confined spaces, with frequent walking and climbing of ladders and stairs. They may also encounter lots of bending, kneeling, reaching and crawling, with the added exertion of pushing, lifting and pulling up to 25 kg.

Shift work may be required, and power system electricians should expect to work away from home for extended periods. Although a 40-hour week is normal, power system electricians may be on call at designated times and may be called upon at any hour in an emergency.
