The paper presents a study based on numerical simulation methods of electrical circuits which analyzes the influence of the internal protection elements of the transformer on atmospheric overvoltage. The difference between the time variation curves of the overvoltages propagated along the high voltage range with and without guard ring is shown as the internal protection element of the transformer.
