Tangential AC Breakdown Strength of Solid-Solid Interfaces Considering Surface Roughness

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1543770

The primary purpose of this paper is to study the influence of the surface roughness and interfacial pressure on the tangential AC breakdown strength (BDS) of solid-solid interfaces experimentally. Three-dimensional surface texture parameters are utilized to characterize the morphology of the polyme...

Interfacial Breakdown between Dielectric Surfaces Determined by Gas Discharge

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1543752

This paper examines the influence of the elastic modulus and applied contact pressure on the tangential AC breakdown strength (BDS) of polymer solid-solid interfaces theoretically and experimentally. In the experiments, three different materials with different elastic moduli, namely cross-linked pol...

On the Tangential AC Breakdown Strength of Polymer Interfaces Considering Elastic Modulus

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1543653

The interfacial breakdown between two dielectric surfaces was reported to represent one of the leading causes of failure for power cable joints and connectors, in which elastic modulus of the dielectric material plays a key role. The primary motivation of this paper is to study the influence of the ...

Examination of Longitudinal AC Breakdown Strength of Dielectric Surfaces as a function of Elastic Modulus

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1502683

This paper examines the influence of the elastic modulus of the polymer insulation on the tangential AC breakdown strength (BDS) of polymer interfaces theoretically and experimentally. In the experiments, four different materials with different elastic moduli, namely crosslinked polyethylene (XLPE),...

Experiences With cable faults located at metallic screen connections

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1477559

Overheating of metallic ground screen connections at accessories of single core cables are the root cause of severe insulation failures in the distribution network. The overheating is due to a high transition resistance of the connections combined with high induced currents in the ground screens dur...

Full-scale case study of a road crossing thermal bottleneck in buried MV cable installation

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1477545

Infrastructures such as road crossings, are often limiting the ampacity of a cable link due to poor thermal properties. In order to fully utilize the true loading capacity of the cable, thermal modelling with correct input parameters should be applied. In this work, a full scale artificial road cros...

The effect of temperature cycling on mechanical and electrical properties of syndiotactic polypropylene

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1375207

Polypropylenes (PP) are a candidate to replace cross-linked polyethylene (XLPE) in medium voltage cables. This is due to its recyclability and potentially lower energy consumption during production. To prove to be an alternative, the PPs must meet the same requirements as for XLPE. The maximum servi...

Determine the Compatibility between Electrical Insulation Fluids and Solid Materials Using a Micro-calorimeter

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1354038

Compatibility between solid and liquid electrical insulation materials has been studied using an isothermal microcalorimeter. This work compares the micro-calorimeter measurements with a simple volume and mass increase for the solid material also capable of indicating incompatibility and compatibili...
