On 19 April 2018, a transformer fire broke out at an electrical substation on Lower Campus Road at the University of Hawaii at Manoa, just outside Les Murakami Stadium. Honolulu Fire Department crews responded at 6:47 p.m. and thick black smoke was visible over Honolulu. Following an investigation, the fire department determined the fire was accidental, caused by an internal malfunction within the transformer that ignited the transformer oil. The blaze caused an estimated 1.5 million US dollars in damage. No injuries were reported in the coverage, and the source does not report any resulting power outage.
An internal malfunction within the transformer ignited the transformer oil, according to the Honolulu Fire Department investigation.
- Oil-filled transformers require regular condition monitoring to detect internal faults before they escalate into oil fires.
- Substations located near public facilities, such as stadiums or campus buildings, should have clear emergency response and communication plans given the risk of heavy smoke plumes.
- Post-incident investigations by fire authorities can help confirm root cause and inform preventive maintenance practices for other transformer assets.
