Low voltage crossing fault excised the REECA1 model

When the voltage drop amplitude is less than 0.9pu and the failure time lasts for 2s, the REECA1 model is removed (the in service button is automatically unchecked), and a circuit breaker is displayed at the output bar. However, I have not set any protection device in the network, may I ask if psse has its own protection device? If I want to modify it, where should I modify it? Looking forward to your reply, thank you very much!
