GE+UR9EH

Description

The GE+UR9EH Module is a Universal Relay used within the GE Multilin protection relay systems. Here’s a breakdown of its functionalities and potential specifications:

Product Name: GE Multilin UR9EH Universal Relay

Product Description:

• The UR9EH module is a versatile relay within the GE Multilin protection relay systems designed for power system applications.
• Protection relays are critical devices that monitor electrical parameters within a power system and can automatically trip (disconnect) circuits in case of faults or abnormal conditions to prevent equipment damage.
• The UR9EH, as a universal relay, offers a wide range of functionalities that can be configured to suit specific protection applications. These functionalities might include:
  • Overcurrent protection: Detects and reacts to excessive current levels.
  • Undervoltage protection: Detects and reacts to abnormally low voltage levels.
  • Overvoltage protection: Detects and reacts to abnormally high voltage levels.
  • Directional protection: Detects the direction of current flow for fault identification.
  • Motor protection: Provides specific protection functions for motors.
  • Communication capabilities: May communicate with other relays or control systems for data exchange and system integration.

Key Features (may vary depending on the model revision):

• Configurable Functions: The UR9EH can be programmed to perform various protection functions based on user configuration. This configuration typically involves setting parameters and logic through software tools provided by GE Multilin.
• Relay Outputs: The module will have relay outputs (contacts) that can be used to trip circuit breakers or activate other control functions based on the detected fault conditions.
• Measurement Inputs: The UR9EH will have voltage and current inputs for measuring electrical parameters within the power system. The specific number and type of inputs will depend on the module variant.
• Communication Ports: Some UR9EH variants might include communication ports (e.g., Ethernet, RS232) to connect to a Human-Machine Interface (HMI) for system monitoring or to other relays/control systems for enhanced protection coordination.
