RelaySimTest
Software for validating protection systems
Don't give hidden faults a chance
RelaySimTest is a software solution for system-based protection testing with OMICRON test sets. The software simulates realistic operational statuses and faults in the electric network to check whether the protection system is working as it should. Thanks to the enhanced testing depth, you'll reliably pinpoint even those logic, design, and communication errors that are hard to detect.

Easy way to test complex and distributed protection systems
RelaySimTest lets you model your power grid in no time and simulate realistic load and fault events. The software comes with templates for selected test situations, saving you valuable time. Nameplate data from the asset is all you need to reliably validate your protection system.
The compact, portable test sets in the CMC family synchronously inject the calculated transient test signals into the protection system. Once testing is complete, you'll automatically receive an adjustable test report with an accurate assessment of the protection system's behavior.
The standardized test procedure ensures your testing meets a high standard of quality every time. Once test plans have been created, you can run them again anytime or adjust them beforehand as needed.
Six good reasons to use RelaySimTest







"RelaySimTest adds those influences to the testing that are present in a real protection system. For me, this is the most important aspect of protection testing."
Ronald Jogaib
Applications Engineer, SEL

“For digital substations and other distributed systems my experience is that RelaySimTest can easily save months of testing and configuration effort while also giving greater confidence that the overall system meets the end user’s requirements. This offers significant benefits to utilities.”
Daniel Mulholland
Principal Engineer - Digital Substations
