IP = IL

VP = VL/1.73

WWYE = VL2/R = 3(VP2)/R

WWYE = 1.73 VLIL

IP = ILO

VPO = VL/2

WOWYE = ½(VL2)/R

WOWYE = 2(VPO2/R)

For Both Wye and Delta (Balanced Loads)

VP = Phase voltage

VL = Line voltage

IP = Phase Current

R = R1 = R2 = R3 =

Resistance of each branch

W = Wattage

IP = IL /1.73

VP = VL

WDELTA = 3 (VL2)/R

WDELTA = 1.73 VLIL

VP = VL

IPO1 = IPO3 = ILO2

ILO3 = 1.73 IPO1

WODELTA = 2 (VL2/R)

Wye and Delta Equivalents

W DELTA = 3 WWYE

Wodelta = 2/3 Wdelta

Wowye = ½ Wwye
