Abstract
This paper is in continuation of Part I. It discusses the dynamic axial risponse of the total transformer system made up of the windings and the clamping structure. The numerical solution presented here accounts for all nonlinearities in the system. The viscoelastic model for representing the dynamic stiffness of the oil-permeated insulation is investigated in detail. Good comparisons between the calculated values and the test values on a 10 MVA transformer support the models and methods developed here.
