KWH Meter Monitoring Design Using Media Power Line Carrier

Abstract

This study aims to design a kWh meter monitoring system design using Power Line Carrier (PLC) media to monitor electricity consumption in real-time through the existing electricity network. This system utilizes an optocoupler sensor to detect kWh meter rotation and convert current and voltage information into digital signals that can be processed. Data obtained from the optocoupler sensor is then sent via the Arduino Uno module connected to the LAN Shield and Power Line Carrier for data transmission. On the receiving side, data is received by the Power Line Carrier Receiver and transferred to the computer via the LAN Shield port. The program developed uses the Arduino IDE on the Arduino Uno microcontroller and Visual Studio on the PC to display the monitoring results in the form of an application. Testing was carried out using the PZEM-004T and ACS712 sensors to ensure the accuracy of current and voltage measurements, as well as the success of data transmission via PLC media. The test results show that the system can transmit electric current data with a 100% success rate in one building with a data transfer speed of 9800 baud rate. This system offers advantages in terms of cost and time efficiency because it utilizes the existing electricity network as a data transmission medium. The main advantages of this system are its ability to perform real-time monitoring and easy integration with existing electrical infrastructure. However, the measurement results indicate the need for further calibration of the sensor to improve accuracy. This study concludes that the use of PLC for kWh meter monitoring is an effective and efficient solution in electrical energy monitoring applications.
