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 phase balance relays provide monitoring and protection in three-phase applications. Two models are available: the ES-47N provides phase unbalance, phase loss, phase reversal/phase sequence protection and the ES-47N/27 provides the same protection as the ES-47N in addition to undervoltage protection. See note below for additional information. Microprocessor-based circuitry enhances functionality and improves performance. Internal diagnostics annunciate when relay function or accuracy is compromised.
