Abstract
This paper describe the design and implementation of an “Automatic method of protecting transformer as an alternative to the fuse protection techniqueâ€. The aim of this paper is to provide an alternative, effective, efficient and more reliable method of protecting fault from power transformer which may arose as a result of overload, high temperature or a high input voltage. Generally, fault may occur in transformers due to the stated reasons. To safeguard the damage of the transformer with the aid and help of microcontroller we monitor and control the entire circuitry. Thereafter regarding the monitoring and control, information about the operation of the parameters would be transmitted to a personal computer for general monitoring and control, which avoid the need of the lines men who had to go to the transformer to re-fix fuses. Lastly, a working system was demonstrated to authenticate the design and possible improvements were also presented.
