Taipei, Dec. 22 (CNA) An unexpected power outage at the second terminal of Taiwan Taoyuan International Airport on Friday, which affected five flights and up to 957 passengers, was caused by a short circuit in a high voltage switchboard.

According to an explanation by Taiwan Taoyuan International Airport (TTIA) Co. Ltd, the short circuit was due to an attempt to power up a newly constructed Evergreen Sky Catering facility, which caused a voltage sag resulting in a power outage in multiple areas of the airport.

Investigations found the power outage was caused by too much current (24,900 amperes), resulting in a circuit breaker trip, as it could only sustain 15,000 amperes. That led to the airport’s main input power of 161 kilovolt high voltage power substation to trip.

Facilities and equipment were immediately checked following the incident and after the scope of the affected area was identified, emergency generators were started within five minutes, according to TTIA.    [FULL  STORY]
