Power to approximately 3,000 customers south of Robert Service Way was lost early Tuesday morning after an insulator on a power pole failed.

Manager Jay Massie of ATCO Electric Yukon said this morning power failed at 1:52 a.m. and was fully restored by 3:59.

The latest outage affected customers all the way to Teslin, including Carcross, Tagish and Marsh Lake, he said.

Massie said the insulator’s failure started a fire at the base of the pole in the vicinity of Canyon Crescent.

The Whitehorse Fire Department responded, and firefighters contacted ATCO when they realized it was an electrical issue, he said.

When the insulator failed, Massie explained, the electricity travelled down the pole to find its way to ground – which caused the fire.

After replacing the insulator, the ATCO crew began restoring power at 3:28 a.m., he said.

Late last Saturday afternoon, a raven flew into a Riverdale substation and cut power to 2,712 customers there and in the downtown area.

Tangerine Technology said that failure caused thousands of dollars’ damage to its equipment and that of its clients.

I'm surprised that Tangerine - being a technology service provider - doesn't have equipment to protect itself against power outages/surges...

What infra-structure was obtained with the last increases?
