Tailored solutions for diverse sectors and challenges.
The ES-47N/27 Phase Balance/Undervoltage Relay is a microprocessor-based protective relay designed to monitor three-phase power systems for voltage imbalance and undervoltage conditions. By continuously supervising phase relationships and voltage levels, the relay helps protect motors, generators, and other critical electrical equipment from damage caused by unbalanced phases or insufficient voltage. Advanced digital technology provides accurate sensing, dependable operation, and internal diagnostics that help identify conditions affecting relay performance. The ES-47N/27 is an ideal solution for industrial, commercial, utility, and power generation applications requiring comprehensive voltage quality and system protection.
