What causes the electrical faults or voltage dips? These electrical faults arise because the smoke and other matter from the fire provide a conductive path, which in layman’s terms results in a “short circuit”. Smoke containing carbon and ash from the bushfire rises and can cause electricity to ‘arc’, or ‘jump’, from one line to another creating a power fluctuation. The power fluctuation is detected by a sensor on the network, which sends a message to a computer that automatically shuts down the line/s to prevent damage and for safety reasons – this happens automatically and within milliseconds. Voltage dips on electricity networks are not unusual and can be caused, particularly on lower voltage networks, by various factors including wildlife and lightning.
