Magnetic saturation and inrush current in transformers

, 2001
The project aims to find a new method, used to discriminate between inrush current and short circuit current based on the waveform discrimination using neural network which is different from the conventional method using the ratio of second harmonic current to differential current.

Defining and Computing Equivalent Inductances of Gapped Iron Core Reactors

, 2011
The paper revisits the fundamental definitions and explores computational alternatives of equivalent inductances of gapped iron core reactors. Unlike in a transformer, the physical meaning of component inductances of a reactor is subject to uncertainty ...
