The measurement error of resistive dividers primarily arises from non-ideal transient response characteristics. When subjected to impulse voltages containing wideband frequency components (DC to several MHz)

the divider behaves as a complex multi-stage RLC network. Particularly

as the rated voltage increases

the influence of distributed capacitance becomes significantly more pronounced

leading to increased errors in time parameter measurements. Consequently

achieving both high amplitude capability and fast response simultaneously in dividers presents a significant challenge. The paper presents a systematic analysis of structural configurations

material selection

and shielding strategies aimed at enhancing measurement accuracy and dynamic performance. Based on comprehensive electric and magnetic field computations

the influence of key structural parameters on stray inductance and distributed capacitance was analyzed. A full-scale distributed parameter simulation model of the divider device was established with high precision. An experimental platform was constructed to conduct critical performance tests on the divider. Moreover

a measurement uncertainty evaluation model was developed

yielding a peak voltage measurement uncertainty of 0.32%. Comparative verification of peak value and time parameter measurement errors was performed with the Finnish National Metrology Institute (VTT MIKES). The results verify excellent peak value consistency

with deviations better than 0.2%. Furthermore

compared to traditional series resistor-capacitor weakly-damped dividers

the proposed configuration exhibits significantly smaller time parameter measurement errors

indicating superior overall measurement accuracy.
