Dear all,
We are working on modelling partial discharges inside solid insulation systems for evaluating the remaining lifetime of insulation system used in electrical equipment.
What do you think are the main requirements from a company for deciding to implement a system that evaluate when a maintenance action or replacement must be done in a critical equipment or component?
In the next link you can download one paper regarding our field of research, if you are interested on evaluating this kind of analysis for a company, please, let me know.

"A Study on the Life Estimation and Cavity Surface Degradation Due to Partial Discharges in Spherical Cavities within Solid Polymeric Dielectrics Using a Simulation Based Approach" is the last publication from my PhD student Johnatan M Rodríguez and me. This paper is published in open access Polymers MDPI
https://www.mdpi.com/2073-4360/13/3/324
In this paper, a brief phenomenological description of the degradation of solid polymeric materials induced by PDs activity in spherical cavities was presented. Then, the accumulated degradation and expected time-to-breakdown or remaining life of the insulation system were calculated using a proposed simulation based approach and a novel damage function. Simulation results showed good agreement when compared with measurements reported by other authors. Finally, the proposed simulation based approach was applied for studying the effects on the degradation rate due to variations on the applied voltage frequency and magnitude. Analytical expressions were determined for the accumulated damage as a function of the applied voltage frequency and magnitude.
My main research is modelisation of flashover of HV polluted insulator and I'm interested to know how we can evaluate evolution of partial discharges on solid insulator.
