Abstract

Currently, electricity utilization is increasing along with the increasing demand for new tides. Electricity usage increases with demand. When installing power capacitors in the electrical network, it is the installation of capacitors in parallel in an electrical installation in the hope of increasing the efficiency of the power factor. This study aims to determine the effect of capacitors on current and voltage. The method used is an experimental method with the aim of knowing the effect of a treatment. The research design carried out by designing power capacitors, determining the load point of installing power capacitors with 2 electrical loads, namely freezers and fans. Next after the installation of the power capacitor is the measurement of the electrical parameters studied. The results of this study show that the addition of power capacitors has an influence on electrical loads. The average voltage and current values in the fan are 210.6 V and 0.97 A, while in the freezer it is 209.5 and 1.105 A.

Abstract

Renewable power plants and alternative power are the best options to meet the world's electricity needs considering the expensive and scarce of petroleum power which has remained the main option in the power generation system. Electric power is something of the main need used by humans. Nationally, the demand for electricity continues to increase to coincide with the rate of population growth, but the rate of demand for very fast power is not matched by the real creation of power zones. Currently, national energy is still focused on fossil energy, namely coal, petroleum, and natural gas. With the increasing use of energy, especially petroleum, until in the future the amount also continues to be limited, fossil energy reserves will decrease and will not be relied on to meet energy needs, because its non-renewable nature requires to quickly explore renewable energy sources. The results of the research tried at an average voltage of 5.12 Volts. As well as the average wind speed of = 4.88 m/s on the contrary, the average rotation speed of the generator is = 8.4 rpm
