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 […]

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 […]

The Resiliency Continuum
Storm damage can wreak havoc on the electrical distribution system and instantaneously create a major impact on those who continuously depend on unfettered access to electrical energy. “Keeping the lights on” is a bedrock principle of utility operations, but is increasingly being challenged by more frequent and turbulent natural disasters. The quest for greater utility […]

Ferroresonance in Inductive Voltage Transformers Or Power Voltage Transformers: analysis, laboratory tests and solutions
A ferroresonance analysis related to HV Inductive Voltage Transformers (IVT) and power Voltage Transformers or Station Service Transformers (PVT/SST) was addressed to develop models based on EMT formulation, enabling detailed ferroresonance risk analyses in specific HV station conditions and helping in the equipment technical specifications (including anti-ferroresonance remedial provisions). The research relied on a comparison […]
