Electric induction motors are the type of motor most commonly operated in industry, and for
this reason technologies that predict faults and reduce the corrective maintenance are of …

When an external short circuit occurs, the axial electromagnetic force increases dozens of
times. Under the effect of the axial short-circuit electromagnetic force, the transformer …

When an electromagnetic transient occurs in a transformer, certain parts of the winding will
be over stressed internally, which in severe cases will lead to the destruction of the winding …

This paper describes a differential algorithm for the protection of a three-phase transformer
to differentiate transient phenomena, such as inrush currents and external faults from solid …

The analysis of the dynamic process of winding destabilization under sudden short-circuit
conditions is of great importance to accurately assess the short-circuit resistance of power …

Reliable and dedicated protection of the transformer is the main requirement in the power
system due to the supervision of a highly expensive equipment transformer. Non‐linear …

Once the short circuit damage accident of a large capacity 500 kV transformer occurs
suddenly, it will seriously affect the safe operation of the power grid. The article expounds on …

A cross-country fault is a fault occurring at two different locations of the same circuit,
simultaneously or with a short time delay and possibly involving different phases, which is a …

The radial instability of transformer winding under short-circuit condition is one of the vital
factors which lead to failures. There have been many analytic and simulative investigations …

The short‐circuit withstand capability of the transformer is crucial to the reliability of power
systems. Research on the short‐circuit characteristics of windings is the basis for improving …
