Option 1 does not solve all the situations (for example, trip logic under autrecloser out of servie).
Option 2 does not solve all the situations since you need to know external information to modify the trip/operation behaviour.
The way to know if there is a three-phase trip is and AND of phsA, phsB, phsC.
Question to 7-5/7-500: Why the standard does not define bi-phsa or three-phase faults?
