TypSwitch attributesPowerFactory Switch Type
Every attribute of the PowerFactory Switch Type (TypSwitch): 48 input parameters, with units and meaning. Copy a name into GetAttribute or SetAttribute.
What TypSwitch is
A switch type: the ratings of a breaker or switch, such as rated current, breaking current and opening time.

| Attribute | Unit | Description | Where |
|---|---|---|---|

Read and write TypSwitch 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("*.TypSwitch", 1)
for typ in types:
print(typ.loc_name, typ.GetAttribute("Inom")) # Rated Current, kA
# An element points to its type with typ_id; t: reads a type value through the element.
for breaker in app.GetCalcRelevantObjects("*.ElmCoup"):
print(breaker.loc_name, breaker.typ_id.loc_name, breaker.GetAttribute("t:Inom"))
types[0].SetAttribute("Ibnom", 40) # rated breaking current 40 kA: 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.
TypSwitch input parameters
The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
