NAGOYA (majirox news) — Bird droppings struck a utility pole insulator, preventing it from transmitting electricity, and causing a power outage that affected about 15,000 homes in three Aichi prefecture cities on Sept. 25, the Chubu Electric Power Co., Inc. (Chuden) said.
Chuden said electricity was halted for about six minutes in the cities of Okazaki, Nishio and Anjo early on Sunday morning.
“It’s rare for bird droppings to cause a power outage,” a spokesman from Chuden’s Okazaki branch said.
The spokesman said Chuden set up wires on the tower where the malfunction occurred to prevent birds from approaching it, but they had been ineffective.
Chuden said the bird droppings landed on a porcelain component acting as an insulator on a steel utility tower functioning as a controller of the electricity flow. The droppings caused a leak in the process, automatically stopping transmission.
Chuden switched power supply to another transmitting station and restored power to the areas affected by the stoppage shortly afterward.
