Design of an Economical Intelligent Frequency Meter

Abstract

Abstract: Vigilantly monitoring the energy consumption of electrical appliances is a crucial aspect of effectively controlling energy usage and expenditures, hence optimizing financial and temporal resources. The utilization of electrical devices can result in various modifications to the characteristics of an electrical power source. Various aspects of an electrical power source undergo modifications when employed for the purpose of powering devices. There have been alterations in the items that necessitate documentation beside the cumulative measurement of meters. This paper discusses the design and implementation of an Arduino-based frequency meter specifically tailored for the measurement of frequency in a three-phase synchronous generator. Additionally, this method was employed to identify instances of malfunction in a three-phase alternating current generator, encompassing both low and high frequencies. The frequency meter that was suggested displayed the measured parameters and the protection condition of each data point directly on the liquid crystal display (LCD) screen. Additionally, a USB cable was employed to facilitate the printing of the Arduino software program in serial mode on a personal computer. A smart monitoring system was developed for various working circumstances using a Bluetooth module. The ZMPT101b AC voltage sensor has been utilized in conjunction with the frequency meter. The frequency was determined by analyzing the signal obtained from the AC voltage sensor, without the need for additional equipment such as a zero crossing detector.
