Protracted power outage specialist "A considerable number of utility poles have time to recover" September 10, 18:59
Regarding the fact that power outages have occurred in a wide range mainly in Chiba Prefecture due to the influence of Typhoon No. 15, Professor Masakazu Kato of Tokyo Denki University, who is familiar with the power system, said that it took some time to restore, “There is a wide range of power outages due to various factors caused by strong winds, such as a considerable number of utility poles falling down or wires being cut by fallen trees. It ’s often not accessible due to fallen trees, etc. Therefore, unless a large amount of equipment and personnel are used, it will not be possible to deal with, and it will take time. ”
He also mentioned that large-scale blackouts occurred in Kansai and Chubu last year due to the typhoon, saying, `` Conventionally, utility poles have been made in a way that satisfies the standards for wind, but recently it has exceeded that. “The damage caused by the wind has increased,” he said.
And as for countermeasures, “It is better to replace with strong power poles and steel towers that can withstand strong winds, but there are a huge number, it is not possible immediately, and it is not realistic. However, it is necessary to make decisions based on the balance between time and cost.
On top of that, Professor Kato says, “It is important to think about how we can protect ourselves when we use electricity in the event of a power failure due to a typhoon or earthquake, and to prepare for it on a daily basis.”
