Measuring relays and protection equipment Part 127: Functional requirements for over/under voltage protection
N EN 60255-127
Annotation
This part of IEC 60255 specifies minimum requirements for over/under voltage relays. The standard includes specification of the protection function, measurement characteristics and time delay characteristics.
This standard defines the influencing factors that affect the accuracy under steady state conditions and performance characteristics during dynamic conditions. The test methodologies for verifying performance characteristics and accuracy are also included in this standard.
The general requirements for measuring relays and protection equipment are specified in IEC 60255-1.
Автоматический перевод:
Реле значения величины и Часть 127 оборудования защиты: Функциональные требования для по/под защите напряжения
Эта часть IEC 60255 указывает минимальные требования для по/под реле напряжения. Стандарт включает спецификацию функции защиты, измерительных характеристик и характеристик с временной задержкой.
Этот стандарт определяет факторы влияния, которые влияют на точность при условиях устойчивого состояния и показателях производительности во время динамических условий. Тестовые методологии для проверки показателей производительности и точности также включены в этот стандарт.
