Power System Safety Rules

Our Power System Safety Rules apply to all TransGrid employees and contractors working on our network.  

These rules were created to keep our people safe when they are exposed to the hazards of working on infrastructure such as substations, overhead lines, high voltage cables, and communication facilities.

In addition to the rules, we expect our employees and contractors to adhere to relevant legislation, codes of practice and guidelines.
