Large power transformers are the most important equipment for the power grid. Their reliability not only affects the availability of electricity in the supply area, but also affects the economic functioning of an energy supplier. The main objective of this work of the development of the transformer testing simulation model on the MATLAB/SIMULINK environment. The designing aspect shall comprise the generator-based and grid-based testing of the transformer and associated results on the same in the SIMULINK. And the methodology shall study the impacts on the grid-connected devices due to testing of the transformers in the grid-based method. The study concluded that there is effectively no effect on the parameter evaluation of OC and SC tests by either source. However, the practical conditions would require grid-based testing that allows a greater range of transformers of various ratings to be tested with high current capability. The impact of fault on the grid can be easily evaluated through location of fault, duration of fault, and dip if occurred. The testing should follow proper timing to avoid such disturbances on the grid. This leads to the rescheduling of the other approved outages or Short Circuit tests.
