Abstract

Based on 220 kV capacitive voltage transformer（CVT） equivalent circuit

a model of ferromagnetic resonance damping of CVT with series saturation reactor damper is built

with which a damp condition is derived theoretically. Combined with the data of 220 kV CVT obtained from Jiangsu Wuxi Nissin Co.

Ltd.

the value of damp resistance is calculated. Simulation results are consistent with the experimental

which is shown that the proposed theory is validated and it can be use to design CVT with no ferro-resonance under certain condition.
