Modelling Electroluminescence Emission in Polymeric Material Using Dimensional Analysis Method

Electroluminescence (EL) technique has captured much attention over the years for its reliable results and data that enhance our knowledge in the initiation of electrical ageing of polymeric insulation. There is growing interest in combining both the EL technique and space charge measurement methods to obtain more profound knowledge of the degradation and ageing of insulation. It is generally accepted that the production of charge carriers within the polymeric material, which can be done through injection, de-trapping, and field dissociation, is a critical component of EL. This research investigates the variables that influence how EL emissions behave, including applied voltage, applied frequency, material ageing, and the types of materials and gases used. It was found that these factors can be helpful in predicting the process of electrical ageing in insulation to avoid any significant catastrophes that may occur. Therefore, it is essential for an EL model to be developed to infer insulation ageing under AC stress with several other factors considered.
