Abstract
Through an analysis of different space charge measurement methods, the paper makes recommendations for ensuring optimal implementations and measurements. The thermal, pressure-wave-propagation and pulsed-electro-acoustic methods are considered. From the underlying physics of these methods, the effect of impedance mismatches and measurement conditions are discussed and simple signal treatments are presented taking into account the case of non uniform materials.
