Innovative Methods for the Survey
​In recent years, the availability of laser scanner instruments capable of operating over long distances (up to a distance of more than one kilometer with the most recent equipment) and the use of survey from drone has allowed us to extend this important methodology, once reserved for applications in the architectural field, the survey of […]

Evaluation of the energy storage systems impact on the Italian ancillary market
The increasing of Renewable Energy Source (RES) generation requires power systems to become more flexible, in order to manage injections variability and uncertainty at various timeframes. Energy storage systems, such as electrochemical technologies, represent a broadly deployable asset, which could support effectively RES deployment. The present paper describes a Mixed Integer Linear-constrained Programming (MILP) model […]

Transparent Fluorescent Silicones
Characterization of Transparent Fluorescent Silicones for Optical Monitoring of High-Voltage Cable AccessoriesThe mechanical and electrical properties of new transparent silicone materials modified with two fluorescent dyes were investigated by measuring stress-strain behaviour, electrical breakdown strength, capacity and dissipation factor, before and after thermal ageing, as well as electrical and optical partial discharges. Mechanical properties of […]

PD in cable accessories
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 […]
