摘　　要：本文介绍的高精度高压电压表,是以标准电压通过电容系统比较分压电阻的电压降,避免分压电阻表面漏电流对测量精度的影响。电压测量的相对误差<10^(-4)。In this paper the voltmeter described is based on comparing the voltage drop across divider resistors with the reference voltage by a system of capacitors that allows one to avoid leakage currents over the divider resistor surface. The relative error of measuring the absolute voltage value is<10-4 .

关 键 词：高压电压表 漏电流 测量精度 相对误差 电压测量
