DESIGN AND IMPLEMENTATION OF ENERGY METER WITH AUTOMATIC LOAD CUT-OFF SYSTEM

ABSTRACT

This work is about optimizing the existing meters that provide meter reading at the end of the month and provide effective management of electricity consumption. This paper presents the design and implementation of an energy meter with an automatic load cut-off feature to enable efficient energy usage in residential and commercial applications. The proposed energy meter integrates accurate power measurement, real-time data monitoring, and automatic load cut-off functionality. The meter employs a combination of hardware and software components to measure the electrical parameters, analyze the power consumption patterns, and implement load cut-off based on predefined criteria. The hardware design of the energy meter comprises a microcontroller unit (MCU), a current sensor, a voltage sensor, and a relay for load control. The MCU acts as the central processing unit and facilitates the measurement and analysis of the electrical parameters. The current and voltage sensors acquire the respective values from the electrical system, and the MCU processes this data to calculate parameters such as active power, reactive power, and power factor. These measurements provide valuable insights into the energy consumption patterns. To implement automatic load cut-off, the energy meter employs a control algorithm based on predefined thresholds and load prioritization. The algorithm continuously monitors the power consumption and compares it to the defined thresholds. When the power consumption exceeds the threshold, the algorithm identifies non-critical loads and activates the relay to cut off their power supply temporarily. The software implementation of the energy meter involves developing a user interface to display real-time energy consumption data and configure the load cut-off parameters. The user interface can be accessed through various means, such as a dedicated LCD display, a webbased interface, or a smartphone application, providing convenience and flexibility to users. In conclusion, the design and implementation of an energy meter with automatic load cut-off presented in this paper offer an effective solution for efficient energy management. The integration of accurate power measurement, real-time data monitoring, and load cut-off functionality enables users to monitor and control their energy usage effectively. The proposed system has the potential to contribute to the development of smart grids and sustainable energy practices by promoting energy efficiency and conservation.
