Monitoring and Control of 3 Phase Electrical Energy Internet of Things (IoT) Based

Abstract

Monitoring the use of electrical energy is generally done by looking at the kWh meter on the installed panel. Power consumption can also be done by measuring directly on the network or electrical load using a Watt meter. Monitoring of 3-phase electrical energy needs to be monitored, especially to find out the amount of energy used in each phase, and on the other hand, it needs to be controlled so that energy use can be controlled, both for each phase or 3 phases. This study aims to design an IoT-based 3-phase electrical energy monitoring and control application. Data on the flow of electrical energy flowing to the load can be monitored from the android, and vice versa can be controlled by disconnecting and reconnecting the energy flow. The PZEM004T component is used as an energy flow sensor, buttons on the application function to disconnect and connect energy flows, and LCD12C and smartphones are used as monitoring devices. The Blynk application is equipped with several switch buttons used to control energy use, along with electronic device control. The data read by the tool can be retrieved and stored in Blynk using the superchart widget so that the operator can see previous history record data sent to emails that have been linked to the Blynk application according to the operator's wishes. The results of the research show that the research tool can display voltage, current, power, energy, and frequency data that can be displayed on a smartphone and LCD. The average error of the mains power compared to the reference meter is 0.02%.

Electric Parameter Measurement on Main Generator Based on IoT for Safe Operational Feasibility

“…The module calculates the power factor, which reflects the efficiency of electrical energy use in the system. The PZEM-004T is capable of measuring the total energy [12] that has been used in the system, which is usually measured in kWh (kilowatt-hours). This module is often equipped with a communication interface such as RS-485 or TTL/UART, which allows users to connect it to a microcontroller or computer for further monitoring and control.…”
