MEA confirms none of the MEA staff causes Suvarnabhumi Airport blackout

14 November 2018 181
On October 24, 2018, Mr. Jaturong Suriyasasin, Director of Corporate Communications of the Metropolitan Electricity Authority (MEA), clarified that the blackout in some areas inside Suvarnabhumi Airport which lasted 10 minutes yesterday (October 23, 2018) and was heavily reported by the press could be confirmed as none of MEA’s operation fault. MEA has investigated and found that such blackout occurred around 9:43 am while MEA and the Airports of Thailand (AOT) have been implementing a maintenance plan for the power stations inside Suvarnabhumi Airport to inspect the 115 kV GIS switchgears and the 24 kV GIS transformers which distributed power to the terminal building and has reserved substitute power supplies during the maintenance for continual use of electricity through a switch operated by the AOT staff. At 9:43 am the switch was turned on and during such action, technical errors occurred, resulting in a blackout in some areas of the passenger terminal building and an automatic startup of the standby generators which caused black smoke coming out of the exhausts, not smoke coming from a fire. 

However, the AOT staff quickly managed to bring back electricity within 10 minutes while adjourning the maintenance of switchgears and transformers under the responsibility of MEA until further notice. Moreover, measures of such accident prevention have been carried out.
