Faulty transformer causes blackout in Edmonton

A faulty transformer has left tens of thousands of people without power in Edmonton, Canada.
Edmonton utility provider EPCOR made a statement on the blackouts, which lasted up to 10 hours.
Officials with the utility provider said a transformer tripped at a substation, but they were still unsure why that happened.
The problems started around 6 p.m. and affected most of the homes and businesses south of Anthony Henday Drive.
“Our crews were dispatched immediately. When they arrived at the substation, minor work was required to switch customers to another transformer,” EPCOR’s Laura Ehrkamp said in a statement.
“Once that work was complete, we were able to restore power for approximately half of the affected customers. Field crews then worked to restore power to the remaining customers.”
