Our paper's primary goal is to use MATLAB to create a tool for transformer design. Manufacturers of transformers can expand their design capacity and save design man-hours by using the suggested methodology, which has several benefits. By running the values through the MATLAB software, we can construct a distribution transformer with any value (power, primary voltage/secondary voltage), a 50 HZ frequency, and a delta/star, shall and core type, oil immersed natural cooling design. In comparison to conventional methods using the same set of constraints, the dimensions as well as the active cost have been decreased. Therefore, this study shows how to use MATLAB to build power transformers in a better and more effective manner. Even though it is anticipated that the present power load will increase by 150% in 2017, it is challenging to find a solution to improve the capacity of facilities, particularly for power transformers. Using MATLAB to create a transformer design will be beneficial in the future.
