GE UR 67H MODULE – Directional Overcurrent Protection Module | UR Series Platform
Engineering Background
The GE UR 67H is a high-performance directional overcurrent protection module engineered within GE Grid Solutions’ Universal Relay (UR) platform — one of the most widely deployed protection relay architectures in global power systems. Designed to IEC and ANSI/IEEE protection standards, the UR 67H delivers precise fault discrimination in complex network topologies where non-directional overcurrent elements are insufficient.
Product Positioning
Targeted at protection engineers and system integrators operating in transmission substations, industrial power distribution, and generation interconnection applications, the UR 67H module slots into the UR chassis ecosystem, enabling modular, scalable protection schemes without full relay replacement. It is the preferred choice for facilities standardized on GE UR infrastructure seeking to extend directional protection capability.

System Architecture & Signal Flow
The UR 67H module operates within the GE UR chassis backplane, receiving analog current and voltage signals from the chassis CT/VT input modules. The directional element computes the phase angle between measured current and a polarizing voltage reference to determine fault direction. A trip output is issued to the chassis output module when both magnitude threshold and directional criteria are satisfied simultaneously. All settings, event records, and oscillography data are accessible via the UR platform’s EnerVista UR Setup software over Ethernet or serial communication ports.

Technical FAQ
Q: Is the UR 67H compatible with all GE UR chassis models?
A: The UR 67H is designed for the GE UR modular chassis platform. Compatibility depends on chassis generation and firmware version. Please provide your chassis model number when inquiring so Konmask can confirm slot compatibility.
Q: Can Konmask supply the EnerVista UR Setup software license?
A: EnerVista UR Setup is available as a free download from GE Grid Solutions. Konmask can assist with version matching to your firmware. Licensed feature upgrades are subject to GE’s software licensing terms.
Q: What is the lead time for the UR 67H?
A: In-stock units typically ship within 3–5 business days. For sourced or refurbished units, lead time is 2–4 weeks. Contact us for real-time availability.
Q: Do you provide IEC 61850 configuration files (ICD/CID)?
A: ICD files are generated by EnerVista UR Setup based on your module configuration. Konmask can provide guidance on IEC 61850 configuration as part of post-sale technical support.
Q: Can this module be used as a standalone relay?
A: No. The UR 67H is a plug-in module for the GE UR chassis platform and requires the chassis for power, I/O, and communication. It is not a standalone device.
