This article presents the harmonic analysis of transformer inrush currents in offshore power systems. Offshore production facilities interconnected by subsea cables are becoming increasingly common, either as new projects or as extensions to existing facilities. Interconnection via a subsea cable introduces a significant shunt capacitance to the source

Prediction and Control of Transformer Inrush Currents
IEEE Transactions on Magnetics, 2015In this paper, we propose a dynamic model of the electrical transformer suitable for the numerical prediction of the inrush currents due to the arbitrary initial excitation of a transformer after a switch-OFF. In particular, the proposed model can be helpful to control strategies to avoid a transient current overshoot, based on the prediction of the ...

Numerical modelling of transformer inrush currents
2012 IEEE International Energy Conference and Exhibition (ENERGYCON), 2012This paper presents an application of a vector hysteresis model to the prediction of the inrush current due the arbitrary initial excitation of a transformer after a fault. The approach proposed seems promising in order to predict the transient overshoot in current and the optimal time to close the circuit after the fault.

Magnetization current inrush in transformers
Electrical Engineering, 1951ANALYTICAL solutions to nonlinear transients such as the phenomena of inrush currents in transformers are notoriously difficult to obtain unless a simple, convenient relationship exists between the dependent variables. Generally the transient may be determined by a graphical or step-by-step process.

Inrush Current of Superconducting Transformer
IEEE Transactions on Applied Superconductivity, 2013Inrush current in superconducting transformers is a little-known phenomenon. Because of its high values and long time, it may lead to loss of superconductivity in transformer's windings. In the article, we present results of inrush current measurements in two superconducting transformers of the same power but different winding geometries.
