Benefits of PHF implementation
1. The effect of improving the aggregate power factor
Harmonic filters use capacitors to absorb harmonics.
The capacitor suppresses harmonics and offsets the inductive reactance of the load to increase the power factor It has the function of making the transformer load loss decrease. This helps to reduce transformer load loss.

［Example case］Transformer capacity =750kVA 6.6kV/400V 3φ load-loss =7,500W load factor =80% monthly operating hours =300h Aggregate power factor =0.75 power factor after improvement =0.95
7,500W×(80%)2=4,800W
1-(0.75-0.95)2=0.377
4,800W×0.377=1,810W
1,810W×300h=543kWh/Month
543kWh/ month×15yen/kWh=8,145yen/month reduction!
1-(0.75-0.95)2=0.377
4,800W×0.377=1,810W
1,810W×300h=543kWh/Month
543kWh/ month×15yen/kWh=8,145yen/month reduction!
：Load loss at 80% load factor
：Improvement in Total Power Factor
：Amount of load loss reduction
：Amount of energy to be reduced per month
：Economic effect of electricity rates of 15yen/kWh

2. Contract power reduction through harmonic suppression
The upper limit of current for each harmonic order will increase or decrease according to the contracted power.
By controlling harmonic currents, the contracted power consumption can be reduced.
［Example case］Rated capacity =85Kva (VFD + DCL） load factor =80%
According to the harmonic outflow current calculation sheet, 510 kW of contracted power is required in the absence of measures.
If you install a harmonic filter, the contract power can be reduced to 120 kW.
510kW-120kW=390kW : Reduction of contracted electricity
390 kW x 1,000 yen/kW = 390,000 yen/month reduction! :Economic effect of a basic charge of 1,000yen/kW
