Short Technical Description. Publication P12y/EN BR/Cc.
Alstom, Electronic Edition, 2003. — 16 pages.Краткое техническое описание на английском языке.The MiCOM Directional/non-Directional overcurrent Relays provide flexible and reliable integration of protection, control, monitoring and measurement functions.
Extensive functionality provides complete protection and control for a wide range of overhead lines and underground cables, from distribution to transmission voltage levels, capacitors bank, generators and transformer generator schemes.Направленные/ненаправленные токовые реле MiCOM обеспечивают гибкую и надежную интеграцию функций защиты, управления, контроля и измерений.
Расширение функций обеспечивает полную защиту и управление широкого диапазона воздушных и кабельных линий разных уровней напряжения, конденсаторных батарей, генераторов и блоков генератор-трансформатор.Table of Contents:Introduction.
