GK Expertise – Numerical Protection Relays
Numerical relays are microprocessor-based protection devices used in electrical power systems. They perform multiple protection functions such as overcurrent, distance, differential, and earth fault protection using digital algorithms. Numerical relays offer more precision, flexibility, and advanced communication features compared to traditional electromechanical relays.
Numerical relays provide several advantages over electromechanical relays:
Multi-functionality: One numerical relay is capable of handling several protection functions simultaneously.
Digital Accuracy: They provide higher accuracy and faster fault detection.
Self-diagnostics: They offer built-in diagnostic features to detect internal failures.
Communication capabilities: Seamless integration with SCADA and various control systems.
Reduced space and wiring: They are compact and require fewer wires for installation.
We manufacture a wide range of numerical relays, including:
Yes, our numerical relays come equipped with advanced communication capabilities, including:
Yes, we offer professional testing and maintenance services for our numerical relays. These services ensure the continuous and optimal performance of the relays in your system.
