A transformer has been destroyed by a fire at a substation in Hyderabad.

The incident took place at the 400 KV sub-station, operated by TS-Transco, in Mamidipally village on the outskirts of the city. Reports show that a 315 MVA transformer was destroyed, along with adjoining transmission system equipment.

Transco engineers at the sub-station alerted the nearby fire stations and switched off the transformer to prevent further damage while diverting the load to other transformers in the sub-stations.

Chairman of TS-Transco D. Prabhakar Rao said the immediate reason for the fire appeared to be internal problems within the 25-year-old transformer.

He continued to say that there would not be any impact on power supply to the city and other area linked to the sub-station as three other transformers were there to take the load. At the time of the incident, the damaged transformer was bearing about 30% of the load and immediately on noticing the fire, the control room switched the load to other sub-stations in the transmission system.
