Setting guidelines

The parameters for transformer tank protection TPPIOC are set via the local HMI
or PCM600.
The setting parameters for the transformer tank protection TPPIOC are described
below:
Common base IED values for primary current (setting IBase) is set in a Global base
values for settings function GBASVAL setting.
GlobalBaseSel: Selects the global base value group used by the function to define
(IBase).
I>: Instantaneous peak current start value in % of IBase.
