Training an artificial neural network to discriminate between magnetizing inrush and internal faults
TL;DR: In this article, a feed-forward neural network (FFNN) was used to discriminate between power transformer magnetizing inrush and fault currents in a digital relay implementation using backpropagation, assuming initially a sigmoid transfer function for the network's processing units.

A Current-Based Solution for Transformer Differential Protection. Part I: Problem Statement
TL;DR: A new approach for transformer differential protection is proposed and a relay that is based on this approach is described and the existing methods for discriminating internal faults from inrush and overexcitation conditions are summarized.

Transformer magnetizing inrush currents and influence on system operation
TL;DR: In this article, the authors discuss the mechanism by which inrush currents are produced, the results of tests and calculations, and studies made with the miniature-system analyzer, and factors that determine the significance, of inrush current from the standpoint of system operation.

Percentage-differential transformer protection
TL;DR: Three-winding transformers present difficult problems for the protection engineer and differential relays which operate on the phase difference between the currents in the different windings are particularly adapted to meet the requirements.
