TypTow attributesPowerFactory Tower Type
Every attribute of the PowerFactory Tower Type (TypTow): 51 input parameters, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What TypTow is
A tower type: the position of each conductor and earth wire on a tower and the conductor types, from which line impedances and couplings are computed.

| Attribute | Unit | Description | Where |
|---|---|---|---|
frnom | Hz | Nominal Frequency | input data |
rearth | · | Earth resistivityearth resistivity | input data |
gearth | uS/cm | Earth conductivity | input data |

Read and write TypTow 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("*.TypTow", 1)
for typ in types:
print(typ.loc_name, typ.GetAttribute("frnom")) # Nominal Frequency, Hz
types[0].SetAttribute("rearth", 100) # earth resistivity 100 Ohm*m: 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.
TypTow input parameters
The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
