RelaySimTest 3.20 Available

December 2, 2019

RelaySimTest is a software solution for system-based protection testing with OMICRON test equipment that takes a novel, future-oriented approach: the test is independent of relay type and relay manufacturer and the often very extensive parameter settings. Instead, it completely focuses on the correct behavior of the protection system. This is made possible by simulating realistic events in the power system.

With RelaySimTest 3.20, the advantages of system-based testing are also available for transformer protection testing. The new features and improvements of version 3.20 include among others:

  • System-based testing for transformer protection (a separate license and a CMC test set with NET-2 interface is required)
    • Transformer protection testing under real-world scenarios
    • No manufacturer-specific test templates needed
    • Testing of CT errors and saturation
    • Internal turn-to-turn and turn-to-ground transformer faults to test restricted earth fault protection
    • Simulation of inrush currents
    • Improved transformer widget
  • Improved power system simulation
    • 50 times faster simulation enables test cases with large power systems
    • Self-igniting fault to test intermitting fault detection and adaptive auto-reclose functions
  • Support of LLX accessories for CMC 430
  • Improved remote connection for end-to-end testing
  • Improved reporting
  • Power system editor improvements
