Sunday’s short power outage, which left about 6,800 Summerside homes in the dark for 10 minutes, was caused by a malfunction at the city’s electrical utility’s substation.
The outage happened between 3:20 and 3:25 p.m. Power was restored between 3:30 and 3:35, said Greg Gaudet, the city’s director of municipal services.
Humidity built up on an insulator caused the outage, said Gaudet.
“There was a malfunctioning insulator at our substation. With humidity, it had tracked over and our protection system tripped because of the faulty insulator, which has been repaired,” he added. “It happens every once in a while, you get the odd insulators that fail whether they got cracked or contaminants on them. It doesn’t happen that often.”
