GE UR8NH Multilin digital relay

High performance and versatility: The UR8NH module is equipped with comprehensive protection functions, including overcurrent, ground fault, overvoltage, harmonic, frequency, directional, and out-of-step protection, and also supports high-precision measurement functions, such as real-time monitoring of power factor and reactive power. These features enable it to adapt to complex grid environments and meet the needs of smart grids, microgrids, and renewable energy access.

Communication capability and compatibility: The UR8NH supports a wide range of communication protocols, such as IEC 61850, Modbus TCP/IP, GOOSE, and SV, which enables it to seamlessly integrate with SCADA systems, distribution automation systems, and protection coordination systems. This powerful communication capability enhances system reliability and flexibility.

Adaptive and Intelligent Protection: The UR8NH module is equipped with an adaptive protection function, which can adjust the protection parameters according to the grid operating conditions to improve sensitivity and reliability. In addition, the module supports self-learning, self-healing and self-adaptation functions, further enhancing system reliability and availability.

Modular design and scalability: the UR8NH adopts an open architecture that supports secondary development and allows users to customize functions and interfaces according to their needs. This flexibility enables the UR8NH to meet the needs of different application scenarios, such as industrial automation, power system protection and new energy generation.

Industrial-grade reliability: The UR8NH module is designed with industrial-grade components and can operate stably in harsh environments. Its wide operating temperature range (-20°C to +60°C) and high immunity to interference and mechanical stress ensure its reliability in complex industrial environments.

Expansion of application areas: The UR8NH is widely used in power plants, substations, grid companies, industrial enterprises, and new energy generation systems (e.g., wind power and photovoltaic) in scenarios such as generator protection, transformer protection, motor protection, and feeder protection. Its versatility and high performance make it an indispensable device in modern power systems.

Intelligence and integration trend: as power systems move towards intelligence and integration, the UR8NH module achieves more efficient fault detection and isolation capabilities through big data and machine learning technologies. This not only improves system safety, but also optimizes power quality and productivity.

The GE UR8NH Multilin UR series is a series of digital relays produced by General Electric for power system protection and control.
These relays are used for various applications, including transmission line protection, transformer protection, and generator protection.
It is related to the CT-VT (current transformer voltage transformer) module. That is to say, it is related to the measurement of current and voltage.
