Abstract：The design method of reference voltage transformer and null detection transformer was introduced. The influence of leakage current between shielding of the transformers was analyzed. The classic incremental buildup calibration method was improved. Both the reference voltage and voltage difference measurement circuit got equipotential protection in zero balance and section voltage balance measurement procedures. The process of self-calibration method was derived. Calibration result was only related to the voltage difference measured by the lock-in amplifier during two balance procedures. The influences of reference voltage transformer, null detection transformer, auxiliary transformer and leakage current between shielding were removed. The calibration results of 1kV inductive voltage divider was presented, and the measurement uncertainty was evaluated, the relative expanded uncertainty was 5.4 × 10-8(k=2).
