A novel two-stage resistance divider to measure high-voltage pulse was developed on the basis of the theory of transmission line.The CuSO4 solution was used as the HV arm of first stage

and the outer shielding structure was exponential curve pattern.The CuSO4 solution was insensitive to skin effect at high frequency.So the divider achieved good transmission performance and stable divide ratio

and its divide ratio could be adjusted conveniently by changing the concentration of CuSO4 solution.The measurement error can be compensated by the lead inductance or serial inductance coils of the LV arms of first and second stages to well satisfy the requirements for high-voltage measurement.
