HARMONIC CURRENT SUPPRESSOR AND ENERGY SAVING SYSTEM BY HARMONIC CURRENT SUPPRESSION

摘要

PROBLEM TO BE SOLVED: To provide a harmonic current suppressor and energy saving system by harmonic current suppression, capable of suppressing generation of a harmonic current by suppressing a harmonic current with a simple configuration capable of being installed at lower cost.SOLUTION: An energy saving system includes a transformer 6 attached to between power lines 5 provided between a power supply 3 and a load 4 on the primary side; a capacitor 8 that forms a parallel resonance circuit 7 resonating at a frequency of a power fundamental wave in a space relative to a winding 6b of the transformer 6 by being attached to the secondary side of the transformer 6.
