What happened
Transformers exploded in St. Petersburg, Florida, as Hurricane Milton passed over the state. The report describes explosions in blue and orange flashes and showers of sparks, one of them outside a residential apartment window, with the equipment carried away by hurricane-force winds. St. Petersburg's airport recorded about four hours of hurricane-force wind gusts, including a peak gust of 101 mph. More than 1.25 million people lost power in the Tampa Bay Area, and outages spread inland as the storm crossed the Florida Peninsula.
Gusts of 76 mph in Lakeland were recorded, and the source says these proved too much for the power grid there. At the time of reporting, more than 2.6 million electrical customers in Florida had lost power.
Contributing factors
The explosions occurred during hurricane-force winds and gusts, and the source describes the Lakeland gusts as too much for the grid there. The source does not state a specific cause for the transformer failures, and no equipment fault, maintenance state or design detail is reported.
Lessons learned
- Assess transformer mounting, bushings and surrounding equipment against extreme wind gusts and wind-borne debris before hurricane season.
- Plan for outages that spread inland well beyond the initial landfall area, and stage restoration crews and spares accordingly.
- Treat exploding or arcing transformers as hazardous, keep the public and residents clear of nearby windows and walkways, and coordinate with emergency services until the equipment is safe.
