Abstract

Scientists and inventors tend to search for ways on how to reduce the electric bills of consumers. For the past few years, different brands of power saving devices came out in the market having a common claim: to reduce electricity consumption. In this study, two of these commercially available power saving devices were assessed and evaluated to determine their functionality and effectiveness. The first part of the study deals with the measurement of electrical parameters of typical appliances at home. The parameters measured include voltage (V), current (A), real power(W), apparent power(VA), and power factor. The parameters of the appliances were measured with or without the power saving devices to them. The effect of the power saving devices was analyzed. For the second part of the study, circuit diagrams were drawn out of each device's circuitry. Using the National Instruments Multisim 11.0electronics simulation software, both devices simulated to understand their nature and operation. The results of the experiment tell that both used in the study do not have the capability to reduce real power consumption. It is also found out that the major component of both devices is a large capacitor. Finally, the results also tell that the power saving devices used in this study operate in the principle of power factor correction.
