KARIMNAGAR: It is not just human beings who need fans and coolers to beat the heat. It may sound surprising but electrical transformers too are to be provided with coolers and mats to ensure that they don't get burnt due to the excess heat across the state.
Officials said that the rising mercury level has become a cause for concern for the electricity department as the electrical transformers, which are situated near the sub-stations, may burn down due to the heat. On a single day, three transformers in the town were reported to have been burnt.
Keeping this in view, the Northern Power Distribution Company Limited (NPDCL) authorities are planning to arrange coolers and water sprinkling system at the transformers.
The AEs have been told to arrange wet mats (khus-khus mats), or gunny bags sprayed with water, around the transformers, wherever necessary. According to electricity department officials, the transformers are designed to withstand temperatures up to 65 degrees Celsius of internal heat.
However, since the external heat on the transformers was crossing 45 degree Celsius, the internal and external temperature of the transformers is rising to 100 Degree Celsius in total.
“In these conditions, the PTs are prone to breakdowns,” an official said. On Friday, Divisional Engineer (electrical), NPDCL, Ch Nageshwar Rao sent out an alert to all assistant engineers to arrange coolers at Power Transformers (PTs) or to provide relief to some portion of the load on the transformers.
