| Abstract: | In the last two decades,the measurement of micro-charge has become the research focus in the field of high voltage insulation measurement.Owing to the difficulty of the design of the charge sensor,some techniques of charge measurement in some cases still have not been solved very well.Approaches for the measurement of spatial charge in solid dielectrics are reviewed,surface charge on the surface of insulator and pre-discharge charge in gas dielectrics. |

| Keywords: | space charge surface charge pre-discharge charge measurement |
