Note: that the value arrived from equilateral triangle:
h = 2
= 0.866 X 100
= 86.6%


VAB = 240/_00
VBC = 240/_-1200
VCA = 240/_-2400
Solve for
VAO = 0.866(240)
Prove that VAO = 207.84V
= 207.84V


Equation:
VAB = VAO+VOB
VAO = VAB+VBO
= VAB+VBO
=240/_00+ VBC = 240/_00+ (240/_-1200)
VAO = 207.84/_-300

Prove that VCO = (0.50)(240)
VCO = 1200
VCO = -VOC
VOC = VOC
= 240/_-1200
= - (120/_-120)
= 120/_-1200+1800
VCO = 120/_600V
