The voltages at the terminals of a balanced load consisting of three 10-ohm resistors connected in Y are:
Vab = 100 angle 0 degrees
Vbc = 80.8 angle -121.44 degrees
Vca = 90 angle 130 degrees
Assuming that there is no connection to the neutral of the load, find the line currents to the load.
Notes:
In the absence of neutral connection, there will be no zero sequence components to solve for.
Considering phase displacements. Phase voltage sequence components:
Van1 = [Vab1 / (sqrt 3)] angle -30
Van2 = [Vab2 / (sqrt 3)] angle 30
Phase currents to load: Ia = Van / R, and so on.
