Function description
Global base values
15.11.2 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,
of GBASVAL functions.
15.11.3 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.
SBase : Standard apparent power value to be used as a base value for applicable functions
throughout the IED, typically
