Abstract

 

Characterization of Transparent Fluorescent Silicones for Optical Monitoring of High-Voltage Cable Accessories

The 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 the new materials are comparable to the reference and the addition of dyes stabilises them against thermal ageing. All materials are equivalent in terms of breakdown strength and capacity. The added value of transparency and fluorescence make them suit-able materials for novel diagnostic applications in HV cable accessories and insulators.​
