Automatic transfer switches, power supply, generator, bluetooth, Automatic Switching


The necessity to develop a cost-effective, smooth, and secure method to automate switching between different power sources resulted in this study. The paper proposes the use of an automatic transfer switch, which automatically switches between the utility power supply and a backup generator, to ensure uninterrupted power supply. The study aims to develop a cost-effective and secure system that utilizes an android device for remote control and monitoring of the power-generating unit. By employing Bluetooth technology, the study eliminates the delays and errors associated with manual source switching. The research specifically focuses on creating an automatic transfer switch compatible with 5 KVA key starter power generators and developing an android application for remote control within a 10-meter Bluetooth range. The system uses electromechanical and solid-state relays for the generator's start/stop sequence and power transmission, respectively.
