2. Effective Z is defined as R cos (θ) + X sin (θ), where θ is the power factor angle of the circuit. Multiplying current by effective impedance gives a good approximation for line-to-neutral voltage drop. Effective impedance values shown in this table are valid only at 0.85 power factor.Oct 1, 2014 · Chapter 9 Tables. Informative Annex A Product Safety Standards.
