This chapter explains how a transformer overcurrent operates by sending a voice message to mobile phones via Bluetooth. This article's primary goal is to address errors and notify the operator of the necessary corrections promptly. The voice announcement through Bluetooth simplifies the operator's workload. When a transformer's secondary current malfunctions, current sensors detect it and send an artificial intelligence-based audible alert through a mobile application. This method is easy to use due to its hands-free announcement feature. When a transformer experiences an overcurrent, the relay continues to trip until the fault is resolved. The necessary steps are executed promptly and accurately to ensure the complete safety of the entire system. Both serious damage and frequent blackouts are prevented by the transformer. To maintain a continuous supply, this model can also be integrated into the power system.
