Function description
Global base values
Application
Global base values function (GBASVAL) is used to provide global values, common for
all applicable functions within the IED. One set of global values consists of values for
current, voltage and apparent power and it is possible to have six different sets.
This is an advantage since all applicable functions in the IED use a single source of base
values. This facilitates consistency throughout the IED and also facilitates a single point
for updating values when necessary.
Each applicable function in the IED has a parameter, GlobalBaseSel, defining one out of
the six sets of GBASVAL functions.
Setting guidelines
VBase: Phase-to-phase voltage value to be used as a base value for applicable functions
throughout the IED.
IBase: Phase current value to be used as a base value for applicable functions throughout
the IED.
