There are many methods that have recently been improved to determine the condition monitoring in most types of single and three-phase transformers. One of these methods is a new method called Sweep Frequency Response Analysis (SFRA), M5300 model. The main concept of such a technique is by adding an amplitude of a wave type of sinusoidal under varied frequencies. The resulting new waveform can be compared with the main waveform. In this paper, there are three types of failures in a 344W single-phase autotransformer consisting of two coils, each containing 100 turns. The first detected failure is the coil movement fault, which is generated by winding deformation through the modeled transformer. The second is the fault caused by a short circuit turn. This type of auto-transformer coil failure gives movement at low, mid, and high frequencies. Finally, a fault is caused by the axial displacement of coils. This type of fault is caused by a short circuit turn across these coils. But in order for the M5300 to generate the necessary results, the Adobe software program has to be attached in order to detect all these kinds of problems. The study of the experienced single-phase auto-transformer coils' frequency, magnitude, impedance, and admittance has been simulated by adding inductors and capacitors to the existing transformer. The 344W autotransformer's results analysis ranged from 100Hz to 2Mz. Furthermore, using both Adobe software and the M5300 device, the tests for 2, 3, and 4 SFRA were planned and simulated.
