继电保护系统
为关键电力系统提供可靠的实时保护和控制。我们先进的保护继电器系统可确保运行安全、最大程度减少停机时间并维护系统完整性。
ES dc voltage sensing relays provide voltage monitoring and protection for applications where dc voltage levels are critical. Three models are available: the ES-74V Over provides overvoltage protection, the ES-74V Under provides undervoltage protection, and the ES-74V Over/Under provides overvoltage and undervoltage protection. Microprocessor-based circuitry enhances functionality and improves performance. Internal diagnostics annunciate when relay function or accuracy is compromised.
