Context: Due to the difficulty of testing large power transformers, the International Electrotechnical Commission standard IEC 60076-5 2006 accepts as an alternative method to validate the short-circuit withstand ability, the forces and dynamic stresses estimation by means of calculation and design considerations.Method: In this paper, the Roth analytical method was used to calculate the axial and radial short-circuit forces in a three-phase 630kVA core type transformer.Results: The calculated forces provided by the Roth method are comparable to the values obtained through modern methods used for electrical transformers design as the finite element method, the difference among calculated values were minimum except the maximum axial forceCon...
