Explosion in a High-Voltage Transformer (787)

At 11:15 pm, an explosion followed by fire occurred in the vicinity of the measurement transformer on an isolated 90,000 V electrical oil transformer at a plant manufacturing technical polymers. Plant personnel placed the installations in safe operating mode, while the backup line and 15,000 V transformer were activated, in coordination with the electric grid operator to keep the sites supply lines open. The risk of falling electrical cables led to closing the adjacent departmental highway, and the emergency crew installed a protective fire hose.
