This paper presents an approach based on the use of transformer no-load and light load
current harmonic analysis to detect the presence of an interturn fault at the incipient stage …

The methodology and test results of a three-phase three-column transformer with a Dy
connection group are presented in this paper. This study covers the dynamics of events that …

Abstract Doubly-Fed Induction Generators (DFIG) are operated for wind energy production,

摘要变压器空载合闸时一次绕组可能产生幅值很高的励磁涌流, 这会对变压器自身和电网稳定
运行造成不利影响, 甚至导致继电保护装置误动作. 该文分析了变压器励磁涌流产生的机理 …

This paper presents results of research related to transformer inrush current reduction with
application of controlled switching of circuit breakers. Procedures for switching instant …

The occurrence of high-amplitude magnetizing inrush current during the energization of a
transformer without load poses significant challenges to the stable operation of both the …

The main goal of this work is the mitigation of inrush current in a three-phase transformer.
This inrush current appears when energizing a no-load or lightly loaded transformer. It can …

This paper proposes a new model for the low‐frequency transient analysis of a transformer,
with a modified equation for calculation of the flux‐current characteristic representing the …

The present work has the purpose of eliminating these transient inrush currents. So this
paper presents a data acquisition system based on dSPACE board 1104, and a laboratory …

This article presents the results of an experimental verification of three-phase Dy transformer
dynamics under no-load conditions. This study is motivated by previous ferroresonance …
