This paper reports the space charge measurement results under actual operation temperature condition for a 23-mm-thick AC XLPE cable. A pulsed electro-acoustic (PEA) method which is newly proposed to measure the space charge characteristics of thick insulation samples accurately was applied. The AC XLPE cable was employed to observe the space charge accumulation clearly. The changes in space charge and electric field distributions corresponding to the changes in temperature and voltage were observed. As a result, we found that the space charge distribution under the heat cycle condition shows complex behavior as the temperature distribution changing. We concluded that it is important to measure space charge characteristics under heat cycle conditions in addition to the conventional space charge measurement under constant temperature conditions to understand the space charge characteristics of the full-size XLPE cable.
