Abstract

This paper introduces the principle of measuring the current of the capacitance by using the turn type arc suppression coil

which has been widely used in power system. An equivalent circuit is established and the error of capacitance current measurement is analyzed

particularly when the system runs in mixed ground operation. And then the paper proves the correctness of this analysis with simulations. Finally the suggestion about how to improve the measurement of the capacitance current of arc suppression coil in operation state of mixed ground operation is proposed.
