Owen Electric is located in Northern Kentucky and serves about 58,000 members. The Boone feeder stretches several miles out from the Boone substation. It has both single and three-phase conductors (12.47/7.2 kV, grounded Wye), with multiple taps branching off. The area is fairly hilly, rural and has lots of trees.
James Bridges, VP of Engineering, explains, “At that time, we believed that trees might be causing the momentary outages, but we did not see any evidence that trees were in the lines.
