ElmTrfstat attributesPowerFactory Secondary Substation
Every attribute of the PowerFactory Secondary Substation (ElmTrfstat): 40 input parameters and 81 result variables, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What ElmTrfstat is
A secondary substation: an MV/LV substation with its transformer, as found along distribution feeders.

Read and write ElmTrfstat in Python
import powerfactory
app = powerfactory.GetApplication() # GetApplicationExt() from outside PowerFactory
for obj in app.GetCalcRelevantObjects("*.ElmTrfstat"):
print(obj.loc_name, obj.GetAttribute("loc_name")) # Name
obj = app.GetCalcRelevantObjects("*.ElmTrfstat")[0]
obj.SetAttribute("loc_name", "Kiosk 12") # rename it- An input parameter is read and written with or without its
e:prefix:GetAttribute("outserv")andGetAttribute("e:outserv")give the same value.
ElmTrfstat input parameters
The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
