When to Contact Your Electricity Distributor Instead of Tensor
Your electricity distributor is responsible for the physical network that delivers electricity to your property, including poles, wires, substations, and transformers. They manage the infrastructure that ensures electricity reaches homes and businesses safely and reliably.
Contact your distributor immediately if you notice any of the following:
- Fallen or damaged power lines
- Sparks, smoke, or fires near power infrastructure
- Sudden or widespread power outages in your area
- Exposed live wires or other safety hazards
While waiting for the distributor to respond, keep a safe distance from damaged equipment or fallen wires and ensure that others do the same. Do not attempt to move or touch any electrical infrastructure yourself. Distributors are specially trained to handle emergencies safely and restore power efficiently. For any network or infrastructure issues, always contact the distributor first rather than Tensor to ensure the situation is managed correctly.
