What happened
On 22 September 2024, the State Emergency Service of Ukraine in the Ternopil region reported an explosion at a transformer substation on Lukiyanovych Street in Ternopil. The service said an SV-110 insulator exploded at a substation described as 110 kW, and that oil burned over about 1 square metre. Rescuers extinguished the fire. Two streets lost power, and the power company was reported to be switching supply to another line. The circumstances were still being established.
Contributing factors
The emergency service reported that an SV-110 insulator exploded and that this led to a small oil fire. The underlying cause had not been established in the report.
Lessons learned
- Insulator failures at substations can ignite insulating oil even when the burning area is small.
- A prepared alternative supply line can limit how long nearby streets remain without power.
- Early reports should record what is known about the failed component without treating it as a confirmed root cause.
