TypTr3 attributesPowerFactory 3-Winding Transformer Type
Every attribute of the PowerFactory 3-Winding Transformer Type (TypTr3): 214 input parameters, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What TypTr3 is
A 3-winding transformer type: rated powers and voltages of the three windings, short-circuit voltages between them, losses and tap changers.

Read and write TypTr3 in Python
import powerfactory
app = powerfactory.GetApplication() # GetApplicationExt() from outside PowerFactory
# Types live in the equipment library of the project.
types = app.GetProjectFolder("equip").GetContents("*.TypTr3", 1)
for typ in types:
print(typ.loc_name, typ.GetAttribute("strn3_h")) # HV-Side, MVA
# An element points to its type with typ_id; t: reads a type value through the element.
for trafo in app.GetCalcRelevantObjects("*.ElmTr3"):
print(trafo.loc_name, trafo.typ_id.loc_name, trafo.GetAttribute("t:strn3_h"))
types[0].SetAttribute("strn3_h", 250) # HV rated power 250 MVA: every element of this type changes- An input parameter is read and written with or without its
e:prefix:GetAttribute("outserv")andGetAttribute("e:outserv")give the same value. - A type is shared: a change to it changes every element that uses it. Read a type value through an element with the
t:prefix.
TypTr3 input parameters
The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
