Repetitive ignitions of electric arc during switching operation may result in generating Fast
and Very Fast Transients (FT and VFT) and thus require analyses to ensure reliable system …

When an unloaded transformer or motor is switched under certain conditions, the circuit
breaker can be exposed to a re‐strike effect that leads to voltage escalation. The effect of …

This paper deals with a modeling of components and calculation of transient overvoltages
that build up on the transformer primary terminals after the transformer has been switched off …

This paper presents a method on how to calculate the cumulative occurrence of
overvoltages during switching off magnetising currents or inrush currents of an unloaded …

The paper describes a simplified transformer model to calculate the transient overvoltage
caused by vacuum circuit breaker (VCB) switching surges. The transients produced by the …

Transformers operating in power networks are exposed to surges occurring during switching
operations. Connecting and disconnecting transformers using Vacuum Circuit Breaker …

This thesis deals with the prediction, improvement and simulation of switching performance
of low-voltage switching devices (LVSDs). A literature review of arc characteristics …

Conclusion: In this letter, the application of a new simplified arrester model is introduced
based on an available measured UI characteristic of an arrester. The model is appropriate …

Purpose The purpose of this paper is to investigate a reliable evaluator of arc re-ignition and
to develop a numerical tool for accurate prediction of arc behaviour of low-voltage switching …

A Vacuum circuit breaker (VCB) model is developed in Alternate Transients Program (ATP).
This model simulates the interruption of high frequency currents and multiple reignitions …
