Design of Load Unbalance on Neutral Current and Losses in Distribution Transformer Using IoT

Abstract

This study examines the current leakage in the neutral in the electricity distribution system, which can cause energy waste and potential safety hazards. This study develops an IoT-based device using the PZEM-004T current sensor to monitor the current in real-time and calculate the financial loss due to current leakage. Tests were conducted under full load and no load conditions for the performance of the device. The results showed that the device is able to detect current leakage with high accuracy, as well as an effective warning system in preventing the risk of electrical accidents. These findings are expected to improve the efficiency and safety of electricity distribution.
