Создана установка для измерения геомагнитно-индуцированных токов (ГИТ), которая установлена на подстанции «Ининская» в Республике Алтай. С апреля 2024 г. проводился периодический мониторинг ГИТ в заземлении нейтрали силового трансформатора с напряжением 110 кВ. Зарегистрированы ГИТ, амплитуда которых достигала 138 мА во время геомагнитных возмущений, что, с учетом параллельного характера заземления подстанции «Ининская» и Ининской солнечной электростанции, означает наличие суммарного ГИТ 1.3 А в заземлении обоих объектов. Показано наличие ГИТ во время наблюдений геомагнитных пульсаций классов Рс3 и Рс5. Обнаружено качественное согласие результатов измерений ГИТ с модельными значениями, рассчитанными на основе измерений на магнитной станции «Байгазан» в приближении однородной проводимости земной коры. Показано влияние сопротивления заземления на регистрируемые ГИТ.

A device for measuring geomagnetically induced currents (GISs) has been created which is installed at the Ininskaya power substation in the Altai Republic. Since April 2024, periodic monitoring of GIS in the 110 kV power transformer grounding neutral has been carried out. GISs were registered during geomagnetic disturbances up to 138 mA, which, taking into account the parallel grounding of the Ininskaya substation and the Ininskaya solar power plant, means the presence of 1.3 A total GIS in the grounding of both objects. GISs are shown to occur during Pc3 and Pc5 geomagnetic pulsation observations. The qualitative agreement has been found between the GIC measurement results and the model values calculated from Baigazan magnetic station data in the approximation of the homogeneous Earth’s crust conductivity. The grounding resistance is shown to exert an effect on recorded GICs.
