Предложение относится к области электротехники, в частности к защите от перенапряжений высоковольтного оборудования сетей с изолированной или компенсированной нейтралью и малыми токами замыкания на землю. Применение ОПН с пониженным уровнем ограничения перенапряжений, логического элемента И, блока задержки позволяет при однофазных замыканиях на землю ограничить перенапряжения до уровня 2 oC 2,3 Vф и отключить выключатель присоединения, к которому подключен ОПН, т.е позволяет сократить длительность приложения к ОПН линейного напряжения сети.The proposal relates to the field of electrical engineering, in particular, to overvoltage protection of high-voltage equipment of networks with insulated or compensated neutral and low earth-fault currents. The use of a surge arrester with a reduced level of overvoltage limiting, a logical element I, and a delay unit allows for single-phase earth faults to limit overvoltages to a level of 2 o C 2,3 V f and turn off the connection switch to which the arrester is connected Linear voltage surge arrester.
