Partial discharges and the electrical treeing represent one of key aspects for the ageing of
the insulating parts of electrical components. To predict the end of life of dielectric systems …

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 …

Polyethylene is one of the most used solid state insulators in electrical power industry. It is
particularly used to electrically insulate high-voltage cables. Under the stresses associated …

The study of cold plasma represents a very active field of applied physics with technical
applications ranging from medical treatments to estimation of aging of electrical components …

The present work is devoted to the modelling of the deterioration process of polyethylene
exposed to reactive plasma. In particular, we present the comparison between two different …

Plasma simulation is getting increasingly important to reproduce technically relevant
configurations in electrical engineering. For instance, simulation tools are used to represent …

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 …

The purpose of this work is to develop an experimental system capable of precisely locating
the partial discharge (PD) events inside the insulating part of axisymmetric electrical …
