Hello,

I checked the API manual. THREEWNDIMPEDCHNG3 has a parameter, intergar8, for resetting the transformer status. I tried to reset interar8=0 for a 3-winding transformer but got the errors below:

ERROR: 0 in-service branches connected to type 1 bus Messages for api FNSL Topology error: 1 bus(es) with bus type code and series element status inconsistencies (000495)

How to reset the 3-winding xfmr status correctly with HREEWNDIMPEDCHNG3? Is it possible just to trip one winding?

Thanks!
