PDF] Frequency Domain Severity Factor ( FDSF )-Transient Voltage Performance-Transformer Outside / Inside

This paper presents a study of the response of the transformer in the frequency domain under switching operation. The applied methodology allows to simulate the behavior of the internal stress al ong windings and also to check whether the insulation system of transformer designed from standard dielectric tests withstands the level of voltage under transient phenomenons. T he study is based on the calculation of Frequency D omain Severity Factor in transformer windings. To perform this calculation, a detailed model based on RLCG l umped parameters frequency-dependent and modal analysis a re applied to obtain the solution in frequency doma in.
