A transformer exploded at the Çorum Organised Industrial Zone (OSB) in Turkey, after which a fire started in the oil tanks supporting the transformer. Firefighters from the OSB Directorate and Çorum Municipality responded, and the fire, which lasted about two hours, was brought under control. Cooling work on the transformer continued afterwards. Once the fire was contained, the provincial governor visited the scene and said the cause could be determined by a technical examination that would follow the cooling operation.

The fire and the resulting outage affected the industrial zone, parts of Çorum city and Sungurlu district, and part of the Samsun-Ankara road. Authorities expected supply to return to normal the following day. Companies in the industrial zone paused production.

Not reported. The source says the cause will be established by a technical inspection after the cooling work.

  1. Oil-filled transformers should have fire separation, bunding and oil containment sized to hold the full oil volume, so that a failure does not spread fire to adjacent tanks or structures.
  2. Operators should review protection and relay settings and inspect transformers after any fault so that internal faults are isolated quickly before a rupture.
  3. Industrial zones fed from a single transformer should have contingency supply or a restoration plan, and operators should communicate expected restoration times to affected businesses and the public.
