Overview

The GE Multilin UR-9HH CPU Module is a central processing unit for the Universal Relay (UR) Series by GE, primarily used in substation automation and power system protection. This module provides the necessary computing power to execute protection algorithms, manage data, and handle communication protocols in various relay configurations.

The UR-9HH is commonly deployed in transformer protection, bus protection, and generator control, where fast and reliable logic execution is critical. It also supports EnerVista UR software, simplifying configuration, diagnostics, and firmware updates. Its modular architecture and compact design make it easy to integrate into existing relay systems.

Technical Data

Typical Applications

• Transformer Protection: Executes logic for differential, overcurrent, and thermal protection schemes.

• Bus Protection Systems: Coordinates fault detection and isolation across multiple feeders.

• Generator Control: Manages voltage, frequency, and synchronization logic in power generation systems.

• Substation Automation: Interfaces with SCADA systems for real-time monitoring and control.

• Industrial Power Distribution: Supports relay logic in manufacturing and heavy industry environments.

For example, utilities use the UR-9HH to process fault data and trigger protective actions within milliseconds, ensuring quick response times. Its support for multiple communication protocols facilitates integration with IEC 61850 networks and legacy systems, ensuring broad compatibility.
