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
Transient simulation
RelaySimTest lets you easily analyze your protection system under transient conditions including CT saturation, power swings, reclosures, or switching on conditions of transformers.
Run tests regardless of protection device type and system complexity
RelaySimTest makes it convenient to test multiple protection devices at the same time from a single PC – whether you're doing end-to-end testing on devices at very different locations or working directly with them in the lab. Plus, you can run tests on protection devices of any type from any manufacturer.
Unique IEC 61850 functional range
RelaySimTest ensures that all IEDs included in the protection concept are interacting as they should – even if you don't have in-depth knowledge of the IEC 61850 data modeling and communication structure. Thanks to the SCD file import, you save valuable time during the configuration process.
Automatically adjusts to protection system behavior
Thanks to its patented Iterative Closed-Loop method, RelaySimTest automatically adjusts the test signals according to the trip and close commands from the protection system. This makes it much easier to test complex logic functions and leaves less room for errors.
Virtual protection testing without hardware
Digital twins of your protection devices let you analyze the protection system without test hardware and physical IEDs. Now you can find any errors in your test plan early on and speed up commissioning and troubleshooting. And there's no limit on the output power or number of test signals.
Full flexibility for future developments
From extra injection points to using central protection systems or main and backup protection concepts, RelaySimTest offers a wide range of options for cascading and controlling test sets and boosters – so you know your protection system will be fully validated every time.
"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.”
