Electrical insulation involves more and more complex structures in which the electric field or the material can be heterogeneous. For testing space charge buildup in such structures, one‐dimensional measurements are still often used owing to their simplicity. The sample complexity may, however, induce spurious effects that can be confused with space charge. In this paper, from the underlying physics of the pressure‐wave propagation (PWP) and the electro‐acoustic (PEA) methods, limitations of the one‐dimensional model are shown and an analysis procedure is given.
