According to the principle structure of the resistor-capacitor voltage-divided electronic voltage transformer, the transient transfer characteristics of the resistor-capacitor voltage-divided electronic transformer after differential integration are analyzed. With relay protection application, the influence of transient voltage transfer characteristics of electronic voltage transformer on fast distance protection is studied. A digital voltage transformer transient test technology scheme based on digital physics hybrid simulation is proposed. The small voltage signal is digitally simulated and amplified by a power amplifier. The physical simulation platform of the electronic voltage transformer resistance-capacitor voltage divider is built and a complete test system is established. The initial time is determined by the mutation detection, and the analog raw voltage signal and the digital signal of the sample are synchronously acquired, then, the transient error calculation of the electronic voltage transformer in the transient process is performed. The feasibility of the test technology solution is verified by the application of the developed test system in the laboratory.
