What happened
The city of Kavala and surrounding area lost electricity for around two hours late on Sunday night after an explosion at a Public Power Corporation transformer shortly before midnight. A small fire broke out but was quickly brought under control.
Lessons learned
- A single transformer failure can cut supply to a whole town, so networks should be able to back-feed supply from other transformers or substations.
- Transformer explosions should be investigated and the cause recorded so that units of similar type and age can be checked.
- Clear public information on the cause and restoration time reduces uncertainty for residents and businesses during an outage.
