Primary & Secondary Testing

The CMC 500 is a modular, multi-phase protection relay test set designed for testing and commissioning protection relays, from conventional electromechanical relays to the latest IEC 61850-based digital intelligent electronic devices (IEDs).

Its flexible hardware architecture, high-performance current and voltage outputs, and comprehensive software ecosystem provide a versatile solution for protection testing, commissioning, and maintenance applications.

The CMC 500 also supports primary injection up to 450 A, current transformer and circuit breaker testing with the appropriate software and options, and reusable commissioning test plans for maintenance, post-event verification, and firmware upgrades.

Key Features

• Modular hardware architecture for a wide range of protection testing and commissioning applications
• Primary injection capability up to 450 A in the UHH configuration for wiring verification and high-current testing
• Advanced IEC 61850 communication for digital substation testing
• Comprehensive software ecosystem for protection testing, commissioning, troubleshooting, and test result analysis
• Reusable automated test plans for maintenance and commissioning workflows
• Enhanced user safety with operational status indicators, an INTERLOCK key, and an interface for external emergency switching-off buttons, reducing electrical hazards during commissioning, troubleshooting, and maintenance
• Cybersecurity by Design, including a secure cryptoprocessor, certificate-based device authentication, and encrypted communication, backed by a secure software development life cycle

CMC 500 is the successor to the CMC 356, offering enhanced flexibility, performance, and expanded testing capabilities.
