Design of a power factor repair tool for UKM

Abstract

The home industry has an important role in improving the community's economy. Energy needs also increase, with this the existing load on the home industry becomes more varied, especially inductive loads that cause a decrease in power factor, this needs to be overcome by improving the power factor by adding a compensator to the network. Because production on a home industry scale is not as continuous in large industries, a power factor improvement tool is needed that works automatically. This study aims to design a power factor improvement tool that works automatically to improve the power factor in the home industry, where the tool works according to network requirements. The Arduino micro controller is used as an automatic controller in the design of this power factor improvement tool, with input using a voltage sensor and a current sensor SCT-013, which is then processed by Arduino to get the power factor value and control the relay to adjust the capacitor requirements to compensate for the inductive load on the network. The results of this study are that the power factor in the household industry can be improved to more than 0.9, the power used in the network is more effective and is absorbed by the load more effectively and the reactive power in the network becomes small or even non- existent.
