PD optical fibre
Progress in optical PD detection for translucent and transparent HV cable accessories with improved fluorescent optical fibresIn a previous paper we introduced sensitive and interference-immune optical PD measurements on HV cable accessories and presented first results. Since then, our investigations tried to cover all important aspects that lead to further improved sensitivity for optical PD […]

Proving reliability of High Voltage cable systems: AC and DC critical aspects
In a changing electrical market, driven by renewable energies, the target is to get wind or solar energy to the cons​umption centers. Nowadays Transmission System Operators (TSO) are worldwide searching for innovative solutions in developing the transmission grid and, as a result, it is likely that the application of extra high voltage AC and DC […]

Testing experiences on extruded cable systems up to 525kVdc in the first third party worldwide laboratory
The booming of renewable power stations (solar and wind mill mainly), the increase use of Interconnectors and submarine cables, the construction of urban substations in big cities with intense population and the need to avoid the use the overhead lines (right of way and so on), are the main factors leading to the increasing amount […]

Technical design requirements and test experiences on Composite Hollow Core Insulators regarding pollution performance under AC and DC stress
This paper is a common approach of manufacturers of insulators, electrical equipment, transmission system and test labs to verify the expected behaviour in laboratory and outdoor tests. For the electrical design of composite insulators, different material properties and shed profiles for AC and DC conditions have to be taken into account respectively, considering the recommendations […]
