have corresponding primary quantity, the 1:1 ratio shall be set for the used analogue
inputs on the IED, For example, HZPDIF.
• Parameter IBase used by the tested function is set equal to the rated CT primary
current.
• Parameter UBase used by the tested function is set equal to the rated primary phase-
to-phase voltage.
• Parameter SBase used by the tested function is set equal to sqrt(3)* IBase* UBase for
three-phase power system.
