Predictive maintenance of transformers to be undertaken by Bescom

The Bangalore Electricity Supply Company (Bescom) is looking to rectify transformer failure  –  the oft-cited reason for interruptions in power supply. A project called ‘predictive maintenance’ undertaken by Bescom along with a private company will enable the power utility to know the actual condition of a transformer before a failure occurs.

A Bescom press release stated the project implementation is under progress in eight divisions of Bescom: north (Peenya), south (HSR Layout), west (Rajajinagar), east (Shivajinagar), Bangalore Rural Circle (Chandapura), Tumkur, Kolar and Davangere (Hiriyur).

It was also added that by December, around 37,500 transformers in the eight divisions will be checked over, to keep a track on unexpected power interruptions and mapping of distribution transformers will be conducted via GIS – the geographical information system.

Images of the distributing transformers will afterwards be taken using thermal image camera in order to identify the hotspots. The thermal images indicating the intensity of overload or excess heat hotspots will be uploaded online.

Although the ‘predictive maintenance’ will be done at periodic intervals, the identified faulty connections will be reticified within a week by operations and maintenance staff, according to the press release.
