Calibrating method and calibrating device for transformer short-circuit impedance tester

The invention discloses a verification method and a verification device for a transformer short-circuit impedance tester, and relates to the field of calibration, verification and detection of power test instruments, and the verification method comprises the following steps: measuring a plurality of basic parameters of the transformer short-circuit impedance tester to be tested by using a standard source, using a standard transformer short-circuit impedance tester and a to-be-tested transformer short-circuit impedance tester to carry out short-circuit impedance testing on the selected transformer, and obtaining a first impedance value and a second impedance value of the selected transformer; and judging whether a relative error between each basic parameter and a set value of the basic parameter is within a preset relative error range or not, if so, judging whether a relative error between the second impedance value and the first impedance value is within the preset relative error range or not, and if so, determining that the to-be-tested transformer short-circuit impedance tester is qualified. According to the verification method and verification device for the transformer short-circuit impedance tester, the reliability of the verification result of the transformer short-circuit impedance tester can be improved.
