Faults that occur during the transmission and distribution of energy usually occur in power
transformers. The interruptions in the transformers, the voltage drops, the sudden …

Recently, an increasing concern has been raised about turn-to-turn faults (TTFs) in power
transformers, because these faults can lead to severe transformer insulation failure and …

In the paper new sensitive algorithms for detection of internal inter-turn faults in power
transformers are described. Such faults are extremely difficult to detect since they induce …

The transformers used in certain stages of electricity production and distribution are the most
important element due to their high costs and long service life. The most important …

this paper presents a novel method of modeling internal faults in a power transformer. The
method leads to a model which is compatible with commercial phasor-based software …

In this paper, a step-by-step method to model power transformer winding faults is presented.
This method is directly applicable to electromagnetic transient programs considering single …

Internal fault detection in transformers provides early warning of electrical failure and could
prevent forced outages with the consequential costs. To detect and diagnose transformer …

Distribution Transformer is one of the most important equipment in the power system. Among
the various faults, internal winding faults comprise about seventy to eighty percent of modern …

Incipient fault detection in transformers provides early warnings of electrical failure and
prevent forced outages with the consequential costs. This paper presents the model …

A power transformer is a very important and expensive asset for a utility. As for any other
power equipment, the transformer is subject to internal faults. The extent of transformer …
