CMC 356 + RelaySimTest

Universal relay test set and commissioning tool -  The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
Software for system-based protection testing -  RelaySimTest is a software solution for OMICRON test sets that simplifies complex protection scheme testing. Its innovative approach validates the correct operation of the entire protection system by simulating realistic power system events. In addition to common tests, RelaySimTest also reveals settings, logic and design errors in the scheme. This paves the way for improved testing quality and time saving testing procedures. Modern protective relays use complex algorithms and adapt to network and failures. Simple function tests are often no longer sufficient for testing such relays. RelaySimTest covers these new demands with a transient simulation of the primary power system. System-based tests are independent from relay type, manufacturer and detailed parameters. The protection behavior is the only thing that counts. With RelaySimTest, you can control all connected CMCs for the test from one PC. Remote CMCs can be controlled via a simple Internet connection. This results in the simplest distributed testing possible for systems such as teleprotection or line differential protection, regardless of how many CMC test sets are used.
