Abstract：A measurement scheme that extracts signals from the ground side was proposed, which fundamentally overcomes the drawback of high risk of taking signals from the high-voltage side in the traditional scheme. Based on the basic PWP method principle for space charge measurement, the composite probe was designed and a portable space charge measurement instrument was built based on it. This measuring instrument can be flexibly applied to many occasions: without applying high voltage, it can independently measure the internal space charge distribution of polyethylene flat samples of different thicknesses; if an external voltage is required, it can also be used with any high voltage sources to complete the measurement. The experimental results show that: compared with the traditional measurement scheme of taking signals from the high-voltage side, this measuring instrument has the same spatial resolution and similar measurement sensitivity.
