GE UR8LV CT/VT Module – UR Series Protection & Control System
When a CT/VT input module fails in a live substation or industrial protection panel, the consequences are immediate and severe: protection relays lose their sensing inputs, differential and overcurrent functions go blind, and the entire feeder or transformer bay must be taken offline for emergency maintenance. In mission-critical power infrastructure — from 110 kV transmission substations to large motor protection panels — even a few hours of unplanned downtime can cost hundreds of thousands of dollars and compromise grid stability. The GE UR8LV CT/VT Module is the precision interface that keeps your UR Series relay fully operational, delivering accurate analog signal conditioning for current and voltage transformer inputs under the most demanding field conditions.
The UR8LV occupies a defined slot within GE’s Universal Relay (UR) platform — one of the most widely deployed digital protection and control architectures in the global utility and industrial automation market. Designed to accept multiple CT and VT input channels, this module provides the analog front-end that feeds the relay’s DSP core with high-fidelity waveform data. Its compatibility across the UR family (including the D60, T60, L90, C60, and F60 relay types) makes it a strategic spare and a first-choice replacement for protection engineers worldwide.

Key Features & Benefits
- Direct Drop-In Replacement: Plug-and-play compatibility with existing UR chassis — no firmware changes or reconfiguration required in most applications.
- High-Fidelity Signal Conditioning: Provides accurate scaling and isolation of CT and VT secondary signals, preserving waveform integrity for protection algorithms.
- Platform Versatility: A single module type supports multiple UR relay variants, simplifying spare parts inventory for utilities and EPCs.
- Robust Industrial Design: Built to GE’s stringent quality standards for operation in substation environments with wide temperature ranges and high EMI exposure.
- Reduced MTTR: Modular architecture allows field replacement in minutes, dramatically reducing mean time to repair versus board-level repairs.
- Genuine OEM Part: Sourced from authorized channels — not a third-party clone — ensuring full compatibility and traceability.
Industry & Equipment Applications
- Transmission & Distribution Substations: Feeder protection, transformer differential protection, bus protection schemes.
- Industrial Power Systems: Motor protection panels, generator protection, tie-line protection in petrochemical, mining, and steel plants.
- Renewable Energy: Wind farm collector systems, solar PV plant MV protection, BESS interconnection protection.
- Rail & Traction Power: Traction substation protection and control systems using GE UR platform relays.
- Data Center & Critical Facilities: Medium-voltage switchgear protection where UR Series relays are specified.
System Integration & Compatible Parts
The UR8LV is designed to integrate seamlessly within the GE UR Series ecosystem. Commonly paired components include:
- UR Series relay chassis (8-slot and 4-slot configurations)
- GE UR CPU/DSP modules (e.g., UR6xx series processor cards)
- GE UR communications modules (IEC 61850, DNP3, Modbus)
- GE UR power supply modules
- GE UR digital I/O modules
When replacing the UR8LV, always verify the chassis slot assignment and relay order code to confirm module compatibility. Contact our technical team for cross-reference assistance.
Our Quality Assurance Process
- Source Verification: All modules are sourced from authorized distributors, OEM surplus channels, or decommissioned utility assets with documented history.
- Visual & Physical Inspection: Each unit is inspected for connector integrity, PCB condition, and label legibility before listing.
- Functional Testing (Refurbished Units): Refurbished modules undergo bench testing on compatible UR chassis to verify analog input response.
- ESD-Safe Packaging: All modules are shipped in anti-static bags with foam cushioning to prevent transit damage.
- Traceability Documentation: Test reports and sourcing documentation available upon request for critical applications.
