| Защита от электромагнитных импульсов от грозовых разрядов на центрах электросвязи |
Предложены руководящие принципы проектирования эффективной системы защиты структуры электросвязи от LEMP. Введено понятие зон молниезащиты в качестве платформы, на которой объединены различные защитные меры: заземление, соединение, прокладка кабеля, экранирование, согласованная система SPD и изолирующие интерфейсы. Приведена также информация о моделировании эффектов LEMP и перечень закупаемого имущества для реализации защитных мер в существующих и новых зданиях. |
