TL;DR: A line of reasoning by which a reliable model of a voltage transformer (VT) can be constructed given substantial uncertainties in its parameters and characteristics is represented.

TL;DR: The problems of estimating the natural and dominating oscillation frequencies in SSVT windings and the voltages on the longitudinal insulation of SSVTWindings under the resonance conditions are considered and the proposed approach is applicable not only to SSVTs, but also to other types of transformer equipment.

TL;DR: An experimental investigation of impulse transients in the windings of a full-scale mockup model of an active part of a 20-kV A SSVT with a rated voltage of 110 kV shows that, unlike in the case of power transformers with disc windings, more significant effects on the insulation are produced when no load is applied on the low-voltage windings.

TL;DR: The algorithm for determination of the parameters of transformer model for calculation of steady state conditions is presented, which provides a good coincidence with experimental values for integral parameters, such as the power loss and the root-mean-square value of magnetizing current.

TL;DR: In this paper, the leakage inductance of small-sized transformers with winding configurations typical for inductive type and station service voltage transformers was calculated using the analytical solution of Maxwell's equations in a two-dimensional axisymmetric statement.
