What happened

Negros Electric and Power Corp. (Negros Power) reportedly energised a replacement transformer at its Asdes Gonzaga Substation, in Bacolod according to a linked article headline, 12 days after the aging unit failed. Emergency assistance was reportedly provided by Primelectric Holdings Inc. and MORE Electric and Power Corp. (MORE Power). A related headline from the same outlet refers to a spare MORE Power transformer and Bacolod's MassKara lights, but the full article was not available, so its account of any effect on supply has not been verified. The failure date, cause and extent of any customer outage are not reported.

Contributing factors

The source describes the failed transformer as aging. No other contributing factors are reported.

Lessons learned

  1. Operators should be able to replace a failed substation transformer quickly, through spare units or mutual-aid arrangements with neighbouring distributors.
  2. Ageing transformers should be identified through condition monitoring and scheduled for replacement before they fail.
  3. Operators should record failure and restoration times so that the duration of any supply disruption can be verified.
