Design and Implementation of Auto-tap Changer for Transformer Using Atmega328 Controller

– Transformers are an important part of the electrical transmission system. ON-load tap variable electrical devices are important in today’s power grid because they allow voltages to be maintained at predefined levels even when loads fluctuate. “As a consequence, the project’s goal is to create an IoT-controlled electrical connection tap changer as well as other important industrial equipment. In this project, the user may select the transformer tap from the Servo tab, which includes 5 volts, 9 volts, 12 volts, and 18 volts. As a consequence, we’ll build the bulk of electrical interface access points for several programmed to handle at the same time”.
