Need or Necessity: Electrical Switchgear Risk Assessment in Australia

The switchgear assembly is a collection of electrical switches, relays, fuses, or circuit breakers used to regulate, protect and isolate electrical equipment.

The switchgear can either power off the device to complete the work or troubleshoot downstream faults.

Although switchgear is usually reliable and works normally, failures (although rare) can be catastrophic. Oil-filled interrupted Switchgear tanks usually burn clouds of oil and gas, which can cause death or serious injury, and cause serious damage to nearby factories and buildings.

The failure of the switch cabinet can also cause serious economic losses.

Molded case circuit breakers should be inspected at least once a year. A routine trip test should be conducted every 3-5 years.

Low-voltage circuit breakers should be inspected and repaired every 1 to 3 years, depending on their operation and working conditions. Whenever the interrupted current of the switch is equal to or close to its rated power, the switch should be inspected and repaired.

Hazards are divided into several main categories, and each category is subdivided into specific hazard sources. A comprehensive checklist helps to thoroughly check whether all safety aspects are covered.

HC 1 Basic health and safety requirements

HC 6 installation, operation, and maintenance

Safety-related risk assessment includes a series of steps:

The switchgear assembly is manufactured to global standards, like IEC 62271 series where design, performance, and testing requirements rule out hazard risks.

Although IEC standards for HV electrical equipment focus primarily on electrical safety, they do not explicitly link the requirements to the hazards of it.
