Zusammenfassung:The authors describe a space charge measurement technique for a long XLPE cable specimen. The length of the cable specimen has been limited in conventional methods, because of the problem of pulse propagation through the cable. The problem was overcome by using the pulsed electroacoustic method, and also by applying the pulse voltage at the outer shield where the piezoelectric device was fixed. A preliminary experiment carried out using a 3.2-mm-thick XLPE cable confirmed the validity of the method.< >
