City staff report on multi-location power outages, crews describe causes and repairs
Summary
City electrical staff described a multi-location outage caused by equipment failures and weather-related line interactions; crews replaced insulators and connectors, isolated a capacitor bank, and advised residents to protect sensitive electronics while repairs were underway.
City electrical staff reported and described a multi-location power outage that affected the east side of town and other neighborhoods, outlining repairs crews performed and possible causes.
Brian (city staff) told the council crews changed out six dead-end insulators and three connectors after a section of lines and connectors burned. He said crews saw a visible fire on a pole and traced intermittent faults that appeared to be related to ice loading and wind: "It had to be the right ice loading, the right angle of the wind this time," Brian said. Crews also investigated arcing near an underpass where wires appeared to be contacting one another and performed localized isolations to restore power.
Staff reported the treatment plant experienced single-phasing and that the generator did not immediately start; a 100-amp fuse at the treatment plant required replacement. On the west side of town staff isolated a capacitor bank near the bowling alley after a capacitor exploded and a fuse repeatedly blew; that bank was left offline pending replacement. Brian said four crew members worked during the event (two on duty, one extra who came in, plus the speaker) and crews were prioritizing safe restoration.
Brian advised residents to disconnect or turn off sensitive electronics during flickering or unstable conditions: "I would recommend your sensitive stuff, shut it off," he said, noting repeated power cycling is hard on equipment. Council members thanked crews for rapid response and snow removal work that weekend.
No formal council action was taken on the outage report; it was presented as an operational update. Staff indicated follow-up work is required to replace failed components and to change the capacitor bank before warmer months to reduce risk of further outages.
