What are the 3 phases of conditioning?

Answer 1

Three phases conditions are:

1. there should be three wires for carrying current and voltage.

2. the current and voltages should be sinusoidal in nature i.e A.C voltages or currents.

3. phase angle should be 120 degree apart for each line voltages or current.

Suppose voltage of the first line is given by:

Va= Vsin(phi)

Then second and third line voltages will be:

Vb=Vsin(120-(phi))

and Vc=Vsin(240-(phi))

where (phi) is the phase angle and V is the supply voltages which has same magnitude in all the three phases.
