Abstract： According to the formation process of residual voltage and the measurement requirements of national standard， those including existing ways， characteristics， methods and requirements as well as the instruments of measurement for residual voltage were described. Based on the various existing methods and different performances of instruments for residual voltage measurement， as well as the requirements of national measurement standards， those problems such as impedance， measurement method and measurement instruments encountered in current residual voltage measurement were pointed out. To solve these problems above， some alternative methods and ideas for specific measurement were suggested.
