PSS/E Simulation. Loss of Field Excitation

[lookingforhelp]

I'm trying to simulate a loss of field excitation in a generator in order to test my relay settings. I have yet to find any PSS/E activites to produce such a simulation. Does anyone know a process to properly simulate a loss of fied situation? Is there a single activity that I could use?

Thanks

Loss of field is usually an offset mho circle. It would be tested the same as a mho distance relay, but with two pickup points, upper and lower.
I'm not sure what a PSS/E activity is.

Are you trying to simulate the transient performance of the electrical system in the region of the generator that has lost its exciter? I imagine you are trying to test the Loexr1 relay model? Is that correct?

Or are you asking how to model the loss of excitation?

It isn't clear what you are trying to do...
