## Narrative

The 167 KVA 7200V-480/240V transformer failed due to age. The transformer had been in service for over 30 years and there was no evidence of a fault external to the transformer itself. The fire was contained within the transformer containment. EMS was notified but had to wait until the power company could turn off power to extinguish the fire, causing it to go over 30 minutes.
