System Wide Outages (4/11/19)
Thursday’s blast of
winter spring unseasonably bad weather led to increased outage activity on our distribution system April 11, 2019. Approximately 2,000 of our members experienced a power interruption in one of 25 separate incidents during the day.
The above totals include 1,025 members in north central Sherburne County whose service was interrupted when a large pine tree fell onto our overhead line along CSAH 11 in Santiago Township at 11:25 a.m., causing West End Substation Circuit 2 recloser to lock out. Our crews removed the tree and power was restored via SCADA to all affected members precisely 1 hour later at 12:25 p.m.
On Friday, March 29, 2019, Energy Park Substation Circuit 3 recloser control was set on hot line tag (an extremely sensitive protection setting that is used for the safety of field personnel) for our line crew to perform hot line work. Concurrently, the Anoka County solar site, which is connected to Energy Park Circuit 3, was brought back online after having been offline for several days due to unrelated construction work nearby. The recloser control’s sensitivity at that moment led it to perceive the subsequent inrush current as a fault and to lock out instantly at 2:42 p.m., leaving 562 consumers in southern Ramsey without power. Service was restored via SCADA to all those affected at 3:14 p.m.
