Transformer fire causes massive outage in Milwaukee

USA, Wisconsin: A large transformer fire at a We Energies substation in Milwaukee left more than 19,000 customers without power yesterday.

An explosion that led to transformer fire caused a short power outage before supply was moved to the other transformer at the substation, but the power had to be completely shut off when the fire crews arrived, reports TMJ4.

“We were more concerned about the energy level. There was 138,000 volts that were still active. That was our main concern, we wanted to make sure we could de-energize that power before we put our people in there in harm’s way,” said Milwaukee Fire Battalion Chief James Hardy.

The secondary outage left lots of homes and business in the area without power. 

The cause of the fire remains unknown at this point.
