PROBLEM TO BE SOLVED: To provide an electric power facility configured so that power saving effect incident to motor operation can be attained, by obtaining a harmonic suppression function on the power trunk line side supplying power to the motor side, without modifying the motor side.SOLUTION: In an electric power facility having a motor 14 being operated by receiving power supply from a power trunk line 12 connected with a power transformer 11, harmonic generation means 13 generating a harmonic voltage becoming opposite phase in the same order as a harmonic voltage becoming a brake force, for the harmonic voltage in the same order becoming a brake force for the rotor, out of the rotational flux of harmonic generated between the stator 14-1 and rotor 14-2, during operation of the motor 14, is provided in the power trunk line 12. |
