The inductive voltage divider is usually used and calibrated at no-load situation, but it also used at taking load situation. For example in the situation of measuring voltage dependence of low voltage capacitors and detecting high voltage bridge, the inductive voltage divider need to take two specific capacitors. This paper have researched the influence of specific capacitive load on its ratio and deduced the analytical formula through related experiments and circuit model analysis when it takes capacitor. And use the method of connecting resistor in series to compensate its ratio accuracy to 1×10-6 degree.
