CHAPTER 6: ACTUAL VALUES
This menu displays metered values for real, reactive, and apparent power, as well as power factor. The "SRC 1" text is
replaced by the name programmed by the user for the associated source (see
).
SOURCES
When VTs are configured in wye, the C60 calculates power in each phase and three-phase power is measured as
When VTs are configured in delta, the C60 does not calculate power in each phase and three-phase power is measured as
where
S is the apparent power
V , V , V , I , I , I are phase voltage and phase current phasors
A B C A B C
V and V are phase-to-phase voltage phasors
AB CB
Î is the conjugate of I
