CMCheck RE for DER Protection Testing

The CMCheck RE software for the CMC 310 enables efficient testing for distributed energy resource (DER) protection. It is specifically designed for testing loss-of-mains (LoM) functions within anti-islanding protection schemes.

The software automates test routines and supports voltage, frequency, rate of change of frequency (RoCoF), and vector shift protection functions. Fast setup, intuitive operation, and minimal training requirements ensure efficient workflows and support compliance with grid standards.

It also enables you to generate compact test reports that include all relevant data.
