Energy department secretary Sandeep Poundrik has directed Patna Electric Supply Undertaking officials to immediately install air break switches in all distribution transformers under its jurisdiction for smooth power supply.
The power company had set a target of installing air break switches — that disconnect power supply to a particular distribution transformer in case of a disruption — in all the equipment concerned under Pesu’s jurisdiction by the end of March 2014, but there has been very little progress.
Poundrik, also the Bihar State Power (Holding) chairman-cum-managing director, on Wednesday directed Pesu officials to complete the work at the earliest.
The deputy general manager (public relations) of the power (holding) company, H.R. Pandey, said: “He directed the Pesu officials to take immediate steps to install the air break switches on all transformers so that power supply was not hampered for a long time in case of a fault in the supply line.”
The directives came at a review meeting of Pesu convened at Vidyut Bhavan.
Installing the air break switches in distribution transformers would help Pesu or the distribution company to restore supply to a large area quickly without affecting the whole region under a power sub-station. The air break switches disconnect power supply to a particular distribution transformer from rest of the system. It helps to isolate a particular section of overhead lines to carry out maintenance work or rectify faults such as fuse-off without affecting the power supply in a large area.
Under Pesu’s jurisdiction, 4,000 distribution transformers supply power to at least 4 lakh consumers. Only 50 per cent of them are equipped with the air break switches.
