The transmission line to Manesar was restored immediately after storm lost its intensity and 400 kV was also restored within four hours followed by immediate patrolling by HVPNL staff.
Similarly, due to heavy wind storm in Yamunanagar, a big tree fell on the 66 kV main bus-bar and damaged the 66 kV Khera-Gobindpuri circuit-I and-II. Consequently three limbs of 66 kV breaker were got broken into pieces and the other connected auxiliaries were also damaged.
Thereafter, the supply was restored through 220 kV substation Jorion within an hour after repair of damaged bus-bar, he said.
Hisar area also had heavy storm, which lead to outage of the circuit of 400 kV Kirori-Khedar line, 220 kV Kirori-Samain and 220 kV Samain- Masoodpur line.
The transmission line was restored in few hours after patrolling by HVPNL staff, he added.
