Research on detention electric charge of electronic voltage transformers based on capacitive voltage divider

This paper presented the basic structure and working principle of the electronic voltage transformer based on capacitive voltage divider (ECVT). The basic characteristic of the transformer has been analyzed. The math model under the transient response has been built. Using Orcad software the transient response was simulated and the math model was validated. The paper analyzed infection of detention electric charge and ascertain the value of secondary resistance divider, which was the basic of designing whole transformer.
