Abstract

Distribution transformers often fail due to constant overloading. This is a major cause of unexpected power outages in rural feeders and small industrial setups. The proposed project presents a cost-effective prototype that uses a micro-controller to automatically balance the load between two step-down transformers. It also provides live current readings on an LCD display. The Arduino Uno R3 board serves as the decision-making unit, continuously monitoring the current load and comparing it to a set value. If the current through the primary transformer exceeds its rated capacity, a relay-controlled switching mechanism connects the secondary transformer in parallel. This allows the two transformers to share the total load. If the total load exceeds the safe rating, the overload is disconnected from the circuit to protect the winding. The prototype was tested on a 24 V, 3 A laboratory-scale prototype and was found to operate within a few milliseconds, maintain the load within the ratings, and accurately display the overload incidents on a screen. The proposed design can be used as an entry-level smart distribution control technique and can be enhanced with IoT/GSM modules for remote monitoring and controlling.
