In a changing electrical market, driven by renewable energies, the target is to get wind or solar energy to the consumption 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 […]
Optical PD detection in high voltage cable accessories A novel method in order to perform diagnosis of the insulation system is optical partial discharge detection. This method does not work with the electrical signals which are caused in case of partial discharges but rather detects the optical signals which are coming up at the same […]
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 […]

Short-term partial discharge monitoring as a diagnostic tool on 400 kV XLPE cable This paper describes the full measurement method and the technique of distributed, fully synchronous short-term partial discharge monitoring at five groups of joints and two groups of terminations on a 400 kV cable in the cable tunnel of 50Hertz in Berlin.Besides the description of […]
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 […]
