Abstract :
Incremental method and normal-reversed reference voltage method used for the calibration of inductive voltage dividers(IVDs) are introduced. Capacitive leakage due to shielding screens of reference transformer and detection transformer is compensated by electronic method. Special shielding structure of reference transformer and detection transformer are presented.
