Lightning activity in Yakutia and its impact on the networks of PJSC Yakutskenergo

Abstract

Abstract It is shown that daily, seasonal and interannual variations in the number of lightning outages in the Central and Western energy district regions of Yakutia correspond to variations in lightning activity in the area where these networks are located. The annual number of lightning outages was from 35 to 65. The daily variation has the form of a one-period wave with a maximum at 19:00 local time and a minimum at 7:00 LT. In the total diurnal variation over 7 years around 7 LT, about two outages were observed, while at 19 LT the total number reached 25. The similarity of daily, annual, and interannual variations in lightning activity and the number of thunderstorm outages indicates the absence of special features in the discharges that lead to thunderstorm outages of high-voltage networks.
