Nearly 60% of the electricity (507 households) was restored within 1 minute, and all of them were restored at 11:09; at 10:5 in Fengshan District, Kaohsiung City, the line tripped due to the fault of the lightning arrester caused by the thunderstorm, causing 1,516 households to lose power, and within half an hour (10:32) All calls were restored.
Taipower pointed out that external forces, natural disasters, and user factors accounted for about 60% of the reasons for the power outage, and Taipower equipment accounted for about 40%. In response to equipment factors, Taipower has accelerated the replacement of old line equipment, strengthened inspections, and fully automated feeder lines to reduce the scope of power outages and shorten the time required for power restoration. For external forces such as bird and beast contact, Taipower has covered the air line by covering it. Insulation, insulation and covering of related switchgear, installation of bird repellents, rodent-proof nets, rodent-proof boards, etc., also strengthen tree pruning and hole filling to block the paths of birds, animals and insects, and try to reduce the contact of birds and animals with power distribution equipment. .
