Development of Three Phase High Power Smart Meter for Energy Management Monitoring System in UniKL MSI

Energy efficiency is defined as using energy in the most efficient way to provide the same service that could have been provided less efficiently. Low energy efficiency will increase greenhouse gas emissions, demand for energy import, and high costs for electrical bills and economy-wide levels. This paper discusses the development of a 3-phase high-power smart energy meter using the Internet of Things (IoT). This meter was designed using a NodeMCU ESP8266 as the main controller device. Three PZEM-004T modules and Split Coil Current Transformer (CT) were the main sensors used in this project. The NodeMCU with the built-in Wi-Fi module allows this system to communicate wirelessly with the cloud server and mobile application. The accuracy of power data measurements proposed by the Smart Energy Monitoring System (SEMS) was tested by experimenting in a laboratory. The result shows all the data measurements of power usage proposed by SEMS had less than 10% error compared with the Power Analyzer. This demonstrated that SEMS had high accuracy and was equivalent to existing measurement devices on the market.
