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 D60 calculates power in each phase and three-phase power is measured as
When VTs are configured in delta, the D60 does not calculate power in each phase and three-phase power is measured as
