Hi Everyone, I am trying to implement Over/Under voltage relay at a bus. The only relay model I can see is VTGDCAT/VTGTPAT in miscellaneous other models but the problem with these model is the breaker time should be same for upper and lower voltage threshold. My question is how to write a python code so that we can have different breaker time for different upper and lower threshold voltage as below ?

voltage (pu) time (s) 1.1 1 1.05 5 0.9 3 0.7 2.2
and so on...

Thanks

voltage V (pu) time (s) 1.1 = 1.1, 1.05, 0.9, 0.7 time(s)= 1, 5, 3, 1 1.05 5 0.9 3 0.7 2.2 2
and so on...
