A challenging problem in the protection of power transformers is the fault detection and
diagnosis (FDD). FDD has an essential role in the reliability and safety of modern power …

This study deals with a method for discrimination between magnetising inrush and internal
fault currents in three‐phase transformers based on sine‐wave curve fitting. A sine wave is …

Interturn short circuit faults are the leading cause of power transformer failures. If not quickly
detected, these faults usually develop into more serious faults that would result in …

This study presents a new scheme for power transformers protection, which is based on the
analysis of the harmonic content of the differential current Park's vector modulus. The …

This article presents an efficient method for discriminating magnetizing inrush and internal
fault currents in three-phase transformers based on the auto-correlation function. For each …

The fault detection process is very difficult in transmission lines with a fixed series capacitor
because of the nonlinear behavior of protection device and series-parallel resonance. This …

Due to the technological development, the electronic power progress and economic stake,
through the use of Wound Rotor Induction Motor (WRIM) has taken more and more places in …

Power systems are increasingly collecting large amounts of data due to the expansion of the
Internet of Things into power grids. In a smart grids scenario, a huge number of intelligent …

Power transformer is one of the most vital equipment in an electrical system and its failure
results in huge economic losses. Amongst the various data driven techniques available in …

Owing to current transformer (CT) saturation caused by a decaying direct current component
in the magnetizing inrush current, the restricted earth fault (REF) protection of a power …
