Tailored solutions for diverse sectors and challenges.
The ES-47N Phase Balance Relay is a microprocessor-based protective relay designed to monitor three-phase power systems for voltage imbalance conditions that can adversely affect equipment performance and reliability. By continuously measuring phase balance, the ES-47N helps protect motors, generators, transformers, and other critical electrical assets from damage caused by unbalanced voltages. Advanced digital circuitry provides accurate sensing and dependable operation, while integrated diagnostics continuously monitor relay health and indicate when relay functionality or measurement accuracy may be compromised. Compact, reliable, and easy to configure, the ES-47N is an ideal solution for industrial, commercial, utility, and power generation applications requiring dependable phase imbalance protection.
