The invention belongs to the technical field of capacitive voltage dividers and discloses a capacitive voltage divider and an intermediate voltage measurement method applied to electrified calibration. The capacitive voltage divider comprises a high voltage arm capacitor C1, a low voltage capacitor C2, a low voltage capacitor lead, a high voltage side shielding sleeve and a low voltage side shielding sleeve. Shielding is introduced in the capacitive voltage divider, the influence of external interference on an intermediate voltage value of the capacitive voltage divider can be effectively reduced, and measurement precision and stability are improved. The intermediate voltage measurement method comprises the steps of first utilizing a temperature sensor to obtain a temperature error, then correcting intermediate voltage obtained by the capacitive voltage divider through practical measurement according to the temperature error, and obtaining an intermediate voltage true value. The method reduces influence of temperature and improves stability of the intrinsic standoff ratio.
