High voltage testing of inhomogeneous composite materials often shows that the stressed volume has a great influence on the result. This paper tries to develop methods of estimating the stressed volume by calculating the theoretical extent of streamer propagation along insulating surfaces. A dynamical numerical model of a certain test setup is used to predict the actual volume tested depending on electrode geometry and peak impulse voltage. The geometry of the test setup as well as the thickness of the Glass Fibre Reinforced Polymer (GFRP) has been varied.
