This paper presents a new approach to model partial discharge and its propagation in the framework of a switchgear's digital twin for partial discharge. It explains the requirements and modelling approach not only for the transfer function between partial discharge source and measurement circuit, but also an advanced modelling approach for the partial discharge source itself. The latter is based on the plasma physic of the discharge. By applying this to a modelling example and a related test setup, the advantages of the chosen approach are demonstrated.
