The Case

WorkSafe VIC v Energy Australia Yallourn Pty Ltd (2023)

On 12 November 2018, an electrical arc flash (or fault) event occurred at a 6.6kV high-voltage circuit breaker in Stage 2, Unit 3 of the power plant of energy supplier and retailer Energy Australia Yallourn. The unit was being returned to service after a planned major outage. The evidence suggests the arc flash occurred when the control cable made contact with live components of the circuit breaker because of a defectively attached infill panel.
