SETUP SIGNAL SOURCES
When VTs are configured in wye, the F35 calculates power in each phase and three-phase power is measured as
When VTs are configured in delta, the F35 does not calculate power in each phase and three-phase power is measured as

S is the apparent power
V , V , V , I , I , I are phase voltage and phase current phasors
