Passengers had a tough time at Terminal 3 of the Indira Gandhi International Airport following a power failure at 3.33pm on Thursday. Normal power supply resumed only by 4.23pm. Till then, the terminal operated with backup power supply. The glitch occurred after the power lines catering to the airport were snapped accidentally by a crane.
“Power supply to T3 was affected due to the Delhi Transco’s grid failure at Damnauli,” said a spokesman of the private airport operator Delhi International Airport Limited (DIAL). “However, within 30 seconds of the grid failure, back-up power was restored through the captive DG sets, and there was no disruption of essential services at the airport,” he said.
“The 220 KV Bamnauli — DIAL Circuit-I got damaged near Rajokri due to touching of boom of a private crane to the tower of Delhi Transco Ltd,” said the spokesman of Delhi Transco.
He said the crane was being used by a hotel to plant date trees in its premises. The 220- KV line was also snapped at Bamnauli-end resulting in shut down of 220-KV system at DIAL and Bamnauli sub-stations.
