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 ac current relays provide current monitoring and protection and may be specified for use in single-phase or three-phase applications. Three models are available: the ES-37 provides undercurrent protection, the ES-51 provides overcurrent protection, and the ES-37/51 provides undercurrent and overcurrent protection. Microprocessor-based circuitry enhances functionality and improves performance. Internal diagnostics annunciate when relay function or accuracy is compromised.
