Lowcost Single Phase Power Analyzer with Automated Data Acquisition and Monitoring System

Abstract

INTRODUCTION

Many consumers are not aware of the electrical consumption of their appliances because they have no idea or background in electrical theory for measuring watt-hour. Power Analyzer was developed to measure the current, voltage and power rating of electrical appliances. The researcher came up with this study to design a low-cost single-phase power analyzer, to make consumers aware of their electrical consumption in order to save electrical power by means of data monitoring system.

METHODS

The methodology used technical investigation processes and implementation procedure for the project. Both descriptive method and New Developmental Product Process were applied in the design and cost of materials. The target is to develop a product with a simple design and low-cost materials. The device is economical but with state-of-the-art technology.

RESULTS

The power system analysis when plugged-in with additional electrical load, the current increases. and reducing other electrical load denotes that power is also decreasing. For every cycle, the power value is updated which means that the value of power varies from time to time based on the behavior of the current entering the load side. When you disconnect all electrical loads, data acquired in the analysis value of power in watts is always zero. The results of LCD and CRT monitors are different. At the CRT monitor, power value is greater than the value at the LCD monitor with the same system unit. When CRT and system units are switch off but still plugged-in the power output still register a consumption. Even if the appliances are turned off but not removed in convenience outlet with the gadget still connected to the electrical load side, it still registers a consumption.

DISCUSSIONS

A low-cost single-phase power analyzer is a measuring device used to measure real time data of electrical parameters such as current, voltage and power rating. This technological innovation helps electrical consumers to be aware about their power consumption. This study focused on hardware and software applications that other researcher can use as a guide for Research and Development. It only means that this is not the end of the research but rather a step towards exploring on the innovations and other capabilities of Single-Phase AC Power Analysis.
