31. The net result is improvement in power factor . 32. One use for this type of motor is its use in a power factor correction scheme. 33. Hence, harmonic currents will reduce the power factor . 34. The power factor of a balanced polyphase circuit is the same as that of any phase. 35. Industrial users may also have extra charges according to their peak usage and the power factor . 36. This non-sinusoidal current leads to harmonic distortion and a poor power factor in the AC supply. 37. The excitation is adjusted until a near unity power factor is obtained ( often automatically ). 38. The controlled rectifier input allows power factor correction. 39. This is because the position of the pointer depends on the power factor , voltage and current. 40. The usefulness of a material in thermoelectric systems is determined by the two factors power factor .
