The engineers of the Punjab State Power Corporation Limited (PSPCL) and Punjab State Transmission Corporation Limited (PSTCL) gathered at Moga on Sunday to investigate the reasons behind the breakdown of all working units at the Bathinda and Lehra Mohabbat power plants on Saturday.
A joint team headed by PSTCL chief engineer RK Sharma visited the Singhan Wala grid at Moga and started a probe.
The units at Bathinda and Lehra Mohabbat first broke down on Saturday afternoon, and once the supply was restored in the evening, the units again tripped at 9.25pm. The rain and storm hitting the region on Saturday night also delayed the recovery. However, the supply was restored in most affected areas by Sunday afternoon.
HT in its report published on Saturday had said that the problem originated in the transmission line of Transco's state grid at Singhan Wala, Moga.
Sharma refused to give details, but he indicated that the PSTCL officials were responsible for the negligence that led to the breakdown.
There was a power cut in large parts of Punjab after the units stopped producing the power. The officials of PSTCL had wrongly put the load on a line, which was connected to the Bajakhana feeder and the cable transfer of this line at Singhan Wala 220 kv grid was damaged.
PSTCL deputy chief engineer SL Garg, who was also supervising the recovery operations, said, "There are four 220 KV lines connected with power grid of the power grid corporation for supply to the state and there is an estimated load between 700 and 800 ampere on these four lines. But the capacity of these four lines is around 750 ampere. Due to overload, one of the lines tripped and the officials, in a bid to divert the supply, connected the wrong lines, which led to the power shutdown."
PSTCL executive engineer Darshan Singh said the cables of power supply were also damaged along with the cable transfer unit and they were trying to restore the power supply at the 220 KV grid.
