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...

Degradation rates in high voltage subsea cables with polymeric water barrier designs

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258256

This paper presents results from numerical calculations of water ingress in a wet designed subsea XLPE cable equipped with a two-layered outer sheath, and results from water tree ageing at different relative humidity (RH) levels in an XLPE cable core. The results from the water tree ageing show that...

Non-Contact Surface Metrology of Degraded Conductor Screens in XLPE Cables

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258147

Stress-induced electrochemical degradation (SIED) structures are likely initiated at the surface of the conductor screen of insulated XLPE cables with stranded aluminum conductors due to water ingress and corrosion. In time such structures initiate severe vented water treeing which significantly red...

Temperature and Electric Field Dependence of the Time Domain Dielectric Response of a Medium Voltage Cable Joint Stress Control Sleeve

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258143

...dependence of the time domain dielectric response of a virgin stress control sleeve commonly used in heat shrink joints has been studied. The result show that the conductivity of the stress control sleeve is strongly temperature dependent and that space charge phenomenon build up even at average fie...

Self-healing composites for high voltage electrical insulation

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258142

A self-healing electrical insulation material for high voltage apparatuses has yet not been developed. Such a material would have been very attractive for electrical components installed in conditions were service failures cause time consuming and very expensive replacements. This paper reports resu...
