Damping the Inrush Current for Current Transformer [PDF]
Proceedings of the Proceedings of the 1st International Multi-Disciplinary Conference Theme: Sustainable Development and Smart Planning, IMDC-SDSP 2020, Cyperspace, 28-30 June 2020, 2020 The inrush current is a highly asymmetric transient magnetizing current resulting from saturation of the core of the transformer caused by excessive growth of magnetic flux in one direction only. The suggested strategy to damp the inrush current is adding an inductor in parallel with the circuit breaker (C.B., which has a very low resistance when it is
