In attached to this FAQ a PowerFactory project with a script inside of Library/Scripts folder can be found.

Script performs following steps:

- Collects all two winding transformers

- Loops through all transformers and accesses relay devices build on the primary side

- Runs a 3 phase maximum short circuit on the secondary side

- Looks at the IDMT block and checks the tripping time.

- In case that the tripping time is higher that 1.4 sec Time setting is being reduced for 0.1 and calculation is repeated as long as the tripping time is above 1.4 sec
