Magnetising inrush current in transformers: an overview
International Journal of Energy Technology and Policy, 2011In India, the failure rate of distribution transformers has been reported very high especially in the rural and remote areas. In these areas, frequent inrush current is produced in distribution transformers during their energisation. The generation of inrush current during each energisation may be dangerous for health of the distribution transformers ...

Controlling Inrush Currents in Inductively Coupled Power Systems
International Journal of Emerging Electric Power Systems, 2005In an Inductively Coupled Power Transfer (ICPT) system, a multiplicity of (moving) loads take power from an elongated conductive loop (track) excited by a current in the range of 15-125A by magnetic induction at a VLF frequency of between 5-50kHz.

Transformer Inrush Current Problems and Solutions
2013Inrush current is magnetizing current which occurs during switching of unloaded transformer on to electric grid. Amplitude of this current can reach high amounts which are 3 to 40 times higher than nominal rated current of transformers and amount of these current grows with transformer power.

Transformer Inrush and Rectifier Transient Currents
IEEE Transactions on Power Apparatus and Systems, 1969Formulas are developed and curves given for the magnetizing inrush current for a single-phase transformer. Series system inductance and resistance are included. The transformer is assumed to have no exciting current below saturation and constant saturated inductance above saturation.
