This work is devoted to modelling the AC breakdown voltage in long oil point–plane gaps with insulating barrier by design of experiments (DOE) method. The authors present an experimental study of a laboratory setup that they designed to carry out the influence of geometrical parameters (the position and diameter of the barrier and the distance between electrodes), involved in the process of breakdown. This study is based on the DOE method. However, this method allowed them to propose a mathematical model of the response and leads to reduce the number of laboratory tests.
