Incremental Buildup Calibration Method of Inductive Voltage Divider

An incremental buildup calibration method of inductive voltage divider was introduced, which comprised two steps, the zero voltage measurement procedure and the section voltage measurement procedure. The reference transformer is connected in series with an auxiliary IVD to compare voltage with the output of IVD to be calibrated. The influence of leakage current of both the reference transformer and the detection transformer can be removed by this method.
