Surface charging of dielectric barriers under positive lightning impulse stress

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1512160

The complex geometry of gas-insulated substations makes it difficult to predict withstand voltages. A key challenge is the characterization of the interaction between electrical discharges and dielectric surfaces. A 60 mm rod-plane air gap with a dielectric barrier is stressed with positive lightnin...

An Engineering Approach to Computational Prediction of Breakdown in Air With Surface Charging Effects

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1508984

This paper presents a dielectric simulation approach for predicting withstand voltage of air insulated power devices. The paper gives an overview of typical evaluation procedures for the basic discharge stages including inception, streamer propagation and leader transition. For selected test arrange...

Breakdown in short rod-plane air gaps under positive lightning impulse stress

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1495788

Prediction of withstand voltages in air-insulated systems are made on the basis of empirical models that are not sufficiently accurate for complex geometries. Better understanding of the spatiotemporal development of electrical discharges is necessary to improve the present models. Discharges in lig...

Streamer Propagation in Rod-Plane Air Gaps with a Dielectric Barrier

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1410150

High-voltage design optimization requires a fun- damental understanding of electrical breakdown mechanisms under different stress situations. The impulse withstand voltage is normally used as dimensioning criterion for medium voltage air-insulated systems as flashover mechanisms in air are rapid. Pr...

Laboratory experiments of melting ice plugs in pipelines by applying direct electrical heating

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1274112

Flow assurance is increasingly challenging as the oil and gas industry is moving towards deeper water and longer transport distances. Formation of hydrate and ice plugs in the pipelines will have major cost impact and must be avoided as removal of plugs is a challenging and time consuming operation....
