Failures due to the degradation of polymeric insulation in components of electrical power
systems are difficult to predict. Partial discharges (PDs) are one of the main phenomena that …

Polypropylene laminated paper (PPLP) is the main insulating material used in the design of
high-temperature superconducting cables due to its good insulating properties in low …

Polymeric insulation employed in electrical power industry undergo irreversible and
unpredictable ageing due to partial discharges (PDs). In particular, the dielectric properties …

Electrical Treeing is one of the main phenomena that influence the aging of insulating
components in the power grid. There are plenty of measurement systems that can detect …

Partial discharges are one of the main aging mechanisms of electrical components. Some
specific types of partial discharges, such as surface discharges and treeing, involve the …

Numerical simulation has played a key role for modelling partial discharges (PDs). In recent
years, semi-empirical approaches have been supplemented by more complex methods …

We report a characterization of the chemical conditions that might cause an electron
emission from a polyethylene surface and trigger a partial discharge in an isolated void. In …
