Summary:The invention discloses a direct-current voltage divider step response test method and system, and the method comprises the steps: collecting a standard voltage signal outputted by a standard voltage divider, a secondary voltage signal outputted by a direct-current voltage transformer, and a decay time constant of the secondary voltage signal through a direct-current electronic transformer tester after a step voltage signal is applied; after the standard voltage signal and the secondary voltage signal tend to be stable, calculating an error value of the collected secondary voltage signal and the standard voltage signal; correcting the step response initial value of the collected secondary voltage signal and the collected decay time constant by adopting the error value to obtain the truth value of the step response initial value of the secondary voltage signal and the truth value of the decay time constant; and on the basis of the truth value of the step response initial value of the secondary voltage signal a
