Three-Phase Power Theory
By switching the Power Network setting from wye to delta, the voltages and
currents I
L1
, I
L3
, I
L2
are calculated, measured and displayed.
When calculating the power, selecting the delta connection will use the two-
wattmeter method (Blondel or Aron) measuring circuit for the calculation.
