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 surges. The difference between the time variation curves of the overvoltages propagated during the high voltage winding with and without guard ring is shown as an internal protection element of the transformer.
