Most northern sectors in the city remained out of power for nearly five hours on Monday as two transformers at the city's biggest electricity sub-station in Kishangarh village developed faults.
There were power outages at sectors 8, 9, 10, 11, 12, 14, 17 and 18, and Industrial Area Phase-1.
UT superintending engineer MP Singh said one of the two transformers at Kishangarh substation, which accounts for transmission of nearly 65% power supplied to Chandigarh, had been repaired in time. “We managed to fix one of the transformers in few hours, but it took considerable time in making the other one operational,” he said.
City residents have been reeling under an acute power shortage since a storm hit the city on June 6. Several transformers had broken down due to the thunder storm and it took the electricity department two days to indentify and fix faults.
Adding to the woes of city residents and the worries of electricity department, of the 49 66-KV transformers in the city, three have been in disrepair for 10 months. These three transformers, located at sectors 39 and 47, and Industrial Area Phase 2, may not be repaired till summer-end.
The department outsources the job of maintenance and service of transformers, but fixing the snag at these non-functioning transformers has taken a considerable time.
