A major power outage hit Gurugram after a fire and blast at the 220 KV power station in Sector-72. An oil leak caused the explosion, disrupting multiple sectors and Rapid Metro services. Power was later restored by DHBVN officials.
A major power outage hit several parts of Gurugram on Friday evening after a fire broke out following a fault in the main transformer at the 220 KV power station in Sector-72, officials said.
Official Cause and Initial Response
According to Sandeep Chugh, PRO of Dakshin Haryana Bijli Vitran Nigam (DHBVN), the disruption was triggered due to a technical fault, which led to an oil leak and subsequent blast in the current transfer circuit.
"Power Supply Restored from the 220 KVA Power Station in Sector 72, Gurugram", the department said, adding that the "Blast Was Caused by Oil Leakage in the Current Transfer Circuit."
Officials further confirmed that "Power Supply to 7 Power Stations Disrupted Due to the Blast in the Current Transfer Circuit", following which electricity department personnel were deployed on-site to carry out emergency repairs.
"Electricity Department Employees Repaired the Circuit and Restored Power Supply," the statement said. The XEN was also present at the site.
Engineers Explain Technical Fault
The fault occurred at around 7:50 pm and led to widespread disruption across multiple 66 KV substations in sectors 15, 38, 44, 46, 52 and 56. Rapid Metro services were also briefly affected but were restored by 8:15 pm, officials said.
According to the XEN (Executive Engineer) of the Haryana Electricity Distribution Corporation, an oil leak in the transfer circuit escalated before the operator could trip the breaker, resulting in a transformer explosion and fire.
"Before the operator could attempt to trip the breaker to prevent a fire, the transformer exploded, and a fire broke out," the XEN said, adding that the blast led to the rupture of the collars of the Current Transformer (CT), which further triggered faults in adjacent systems.
Power Restored, Replacement Work Underway
Due to the incident, two major 220 kV substations in Sector 56 and Sector 52 were shut down, along with five linked 66 KV substations, resulting in a large-scale blackout across the network, another Executive Engineer, Anil Malik, added. Rapid Metro services, which operate from the Sector 56 power station, also came to a halt at 7:50 pm but were restored around 8:25 pm.
"By 10:10 pm, the department had fully restored the entire system on its end. Currently, there is no impact on the power supply," officials said.
Authorities also stated that the primary cause of the fault and damage was excessive heat (thermal heating). Restoration work has been completed, and replacement equipment has been dispatched to the site, with officials expecting full replacement of damaged components within the next 2-3 hours. "No further issues are anticipated during the night," officials added. (ANI)
