Smart $; Mwdkmpr?? Each of the 3-lines will carry current for the conditions cited in Smart $?s post. Following is a solution using what I call the GiFiES (pronounced Jiffy?s) method, where: Gi => Given; Fi => Find; E => Equation(s); S => Solution
Given:
VAB=208∡+120⁰
VBC=208∡0⁰
VCA=208∡-120⁰
And if PF = 1.0, or unity, then,
IAB=200∡+120⁰
IBC=200∡0⁰
ICA=0
Find:
Line-Currents, IA, IB, and IC
Equations:
IA = IAB ? ICA
IB = IBC ? IAB
IC = ICA ? IBC
Solutions
IA = 200∡120⁰
IB = 346∡- 30⁰
IC = 200∡180⁰
