OMICRON - CMCLIB REFxx | INTERFACE ADAPTER FOR ABB PROTECTION RELAYS
 
The OMICRON CMLIB REF6xx is a specialized interface adapter designed to connect CMC test sets with protection relays featuring sensor inputs, such as the ABB Relion series (e.g., REF615, REF601). It bridges standard test hardware with modern non-conventional instrument transformers by converting low-level output signals into accurate differential signals tailored for Rogowski coils and voltage dividers.
 
Features & Benefits
 
Seamless Sensor Integration: Connects CMC test sets directly to relays utilizing low-power instrument transformers (LPITs), Rogowski coils, and capacitive voltage dividers.
Low-Level Signal Conversion: Accurately converts low-level analog outputs from CMC test sets into precise differential signals required by advanced protection devices.
Broad Compatibility: Fully compatible with OMICRON test systems, including the CMC 356, CMC 353, CMC 256 Plus, and CMC 850.
High Measurement Fidelity: Engineered with precision components to ensure high-accuracy signal reproduction with minimal phase and amplitude error.
Compact & Field-Ready: Lightweight, rugged construction optimized for robust performance during on-site substation testing and commissioning.
 
Material & Build
 
The OMICRON CMLIB REF6xx is housed in a compact, durable, and field-proven enclosure built to withstand demanding substation and industrial testing conditions. Its internal circuitry utilizes high-precision components to maintain signal integrity and long-term reliability in harsh environments.
 
 
Use cases
 
Testing and commissioning of ABB Relion protection relays (such as REF615) equipped with sensor inputs
Simulation of Rogowski coils and low-power voltage/current sensors during secondary injection testing
Digital and hybrid substation validation combining standard CMC test sets with modern sensor-based architectures
