OMICRON - CMC 500 | RELAY TEST KIT
 
The OMICRON CMC 500 is an advanced, modular multi-phase protection relay testing system and commissioning tool designed to deliver high efficiency, cybersecurity by design, and multi-layered user safety. It empowers engineers to perform comprehensive testing, validation, and end-to-end protection verification across all generations of relays—from high-burden electromechanical units to modern numerical and fully digital IEC 61850-based substations.
 
Features & Benefits
 
High-Flexibility Outputs: Equipped with versatile configurations providing up to seven voltages and ten currents to address complex multi-phase testing demands.
Advanced Digital Substation Integration: Full support for modern communication protocols, including IEC 61850 (GOOSE, R-GOOSE, MMS) and Sampled Values with configurable datasets.
Cybersecurity by Design: Hardened against cyber threats featuring an integrated Trusted Platform Module (TPM 2.0), unique device authentication, secure boot, and encrypted PC communication.
Multi-Stage User Safety Concept: Compliant with ISO 13849-1, featuring an interlock key, operating mode button, bright status indicator signal lights, and external emergency switching-off button interfaces for secure testing setups in line with EN 50191.
Dual Testing Paradigms: Seamlessly combines detailed parameter testing via Test Universe with realistic grid behavior simulations using RelaySimTest to reduce testing efforts by up to 80%.
Comprehensive Asset Diagnostics: Supports functional checks on auxiliary assets such as current transformers, circuit breakers, transducers, and specialized traveling wave protection relays.
 
Material & Build
 
The OMICRON CMC 500 is engineered as a lightweight, robust, and highly portable field-ready test set (weighing between approx. 12.1 kg and 15.6 kg, depending on the variant). Built with precision electronics and hardened industrial components, every unit undergoes multi-day endurance testing prior to delivery to ensure long-term reliability in demanding substation environments.
 
 
Use cases
 
Protection relay testing across all generations (electromechanical, numerical IEDs, and IEC 61850 devices)
Full validation of hybrid and fully digital substations using GOOSE and sampled values
Primary and secondary injection testing to verify entire signal paths down to relay terminals (with high-current accessory support up to 450 A)
Rapid troubleshooting, multi-functional real-time measurement, and automated documentation of test results.
