| Руководство по обеспечению помехоустойчивости от высотных электромагнитных импульсов для центров электросвязи |
В Рекомендации МСЭ-Т K.78 определяются требования по защите от излучаемых и кондуктивных помех, создаваемых высотными системами генерации электромагнитных импульсов (HEMP) для оборудования, установленного в центрах электросвязи и выполняющего функции коммутации, передачи, радиосвязи и распределения энергии. Эти требования включают методики и уровни испытаний на помехоустойчивость оборудования электросвязи при конкретных условиях монтажа. Уровни помехоустойчивости могут быть улучшены путем применения концепции защиты на основе устройств, предохраняющих от скачков напряжения (SPD) для снижения отрицательного влияния помех и электромагнитного экранирования зданий и корпусов оборудования. |
