Abstract

The transfer function model of ECVT（electronic capacitive voltage transformer）is deduced and established.Both the frequency characteristic and the normal frequency domain of ECVT are analyzed; meanwhile

the measurement performance of ECVT for various transient and steady-state disturbance signals is studied in details.Research results show that

within the normal measuring frequency domain

variety of transient disturbance signals as well as harmonic signal required in national standard could be measured accurately by ECVT

and ECVT has excellent restoration capacity for primary signal.
