CB Simulation: Test View
CB Simulation simulates the auxiliary contacts of a circuit breaker (CB) during a test (for relays requiring a connection and operation of those contacts for proper functioning). Depending on the available binary inputs and outputs, it is possible to simulate one-pole and three-pole operation of the CB. A time signal display shows the actual situation. The timing parameters and the mode of operation of CB Simulation is specified in CB Configuration. The actual simulation is controlled by the CMC firmware, allowing real-time responses of the simulated auxiliary CB contacts (52a, 52b) to trip and close commands. CB Simulation is supported by CMC 356, CMC 353, and CMC 256plus.
