The working principle of electronic voltage transformer based on resistive -capacitive divider is introduced, and the focus of description is that resonance boosting is carried out for 110 kV electronic voltage transformers by using compensation reactor connected in parallel with GIS pipeline. Compared with the experimental data of traditional boosting methods for cascade transformer, it is demonstrated that the parallel resonance boosting has the characteristics of simple operation, small primary current, high security and reliability and good applicability in case of GIS pipeline.
