According to the preliminary enquiry report received, on the power tripping during the Press Conference in the National Media Centre of Piyush Goyal, Minister of State (IC) for Power, Coal and New and Renewable Energy on 20.5.2016 there was a power failure at 11.25 A.M. from the NDMC side.
The National Media Centre has a back-up of 4 Gensets – 2 Gensets of 500 KVA and 2 Gensets of 750 KVA which are in a auto mode. Soon after the power failure, the sets started on automode but due to surge in requirement of power the air circuit braker of the supply tripped and load automatically transferred to 500 KVA Gensets.
Since the power supply was not stable in automatic mode, PIB officials took the decision to put the Gensets into manual mode and maintain the supply without any further tripping till the end of the Press Conference.
The power supply of NDMC was restored after 45 minutes at 12.10 P.M. but in order to avoid further tripping, the supply was maintained on DG sets.
DG, PIB had earlier in the afternoon ordered an enquiry into the power incident and sought a report from the officials of PIB soon after the Press Conference.
