要約(英語): The waveform immediately after the start of measurement has been used as a calibration waveform in the space charge measurement for HVDC cables. However, space charge accumulation may occur at high temperature during the acquisition of the calibration waveform, which may affect the accuracy of signal processing. In this study, we proposed a method to apply the waveform at the room temperature for the correction of the waveform at high temperature, for the space charge is unlikely to be accumulated at room temperature. A correction method of signal distortion under temperature was studied. As a result, space charge profiles considered to be reflected the temperature were obtained, and it is supposed that it improves the reliability of space charge profiles at high temperature.
