Operating Software

We continuously develop and maintain our operating software options to give you the best support possible during your various protection testing tasks.

Test Universe

Specifically designed for settings-based protection testing with a high degree of automation, our modular software Test Universe offers numerous functions and application-optimized test modules that save you valuable time.


With its novel and future-oriented approach our software solution for system-based protection testing, performs tests independent of relay type, relay manufacturer, and offers extensive parameter settings. It focuses on the correct behavior of the protection system by simulating realistic events in the power system. Use RelaySimTest to easily detect hidden errors in your settings, logic, and protection system design and raise the quality level of your tests substantially.

CMControl P

Use CMControl P for quick and easy manual testing. CMControl P is available as an App for Android tablets and Windows PC, or as a dedicated front-end device.


The open programming interface CMEngine enables you to integrate the CMC test sets into your own testing environment and control them within any type of application.

EnerLyzer / EnerLyzer Live

With this software the CMC test set becomes a multifunctional measurement and recording unit. You can use EnerLyzer/EnerLyzer Live in parallel with the software used for operating your CMC.


Operating Software Packages

We offer our operating software in four pre-configured packages. Any package can be extended at any time by ordering additional single modules or optional add-ons. Additionally, we offer special add-ons for testing in IEC 61850 environments, measurement equipment testing and calibration.

Essential Package

If you are only looking for the software modules for some general testing tasks, the Essential Package will provide you with the most important generic Test Universe modules which allow you to cover various applications.
For protection testing tasks you should add modules for the protection functions that need to be tested.
