Power factor depends on the connected load on that perticular
phase due to heavy inductive load ( Induction motor)but you
are telling it is different in all three phase it is due to
the mismatch in the phase impedence in the motor winding

In AC if the direction of current keeps reversing every half cycle, how does it propogate through the transmission lines?

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
