A STUDY ON ELECTRIC SAVING IN A WATER-JET WEAVING FACTORY

Abstract

The purpose of the research is to investigate the factors, which consider having an effect on electric saving in a water-jet weaving factory.
The findings reveal that there was significant effect on electric saving from costing 0.62 Baht/Yard to 0.46 Baht/Yard. From the results obtained, it was found that:
1) By changing from a conventional motor to a high efficiency motor has the most significant effect on electric saving at 63.17 %.
2) Adapting from T8 light bulb to LED-T8 light bulb also has a significant effect on electric saving at 18.16 %.
3) Varying the meter rate to TOU-rate along with alternating staffs’ working-schedules during weekend and holiday periods result in electric saving at 12.40 %.
4) Adjusting the power factor by correcting the capacitor results in electric saving at 6.27 %.
5) By monitoring and controlling electrical power peak-load, nevertheless, the result is not significant on electric saving.
In conclusion, the findings of the study on electric saving in a water-jet weaving factory reveal that by changing to high efficiency motor has the most significant effect on electric saving regardless the highest investment cost among others factors. The result of electric saving is considered cost-saving advantage and will help increase the competitiveness of the weaving industry.
