Behavioral Modeling and Analysis of Ground Current in Medium-Voltage Inductors

This letter proposes a behavioral model for analyzing the ground current in medium-voltage (MV) inductors. The impedance between terminals and connection of inductors is measured by analyzer, which capacitive at low frequency. In order to characterize this impedance, multistage paralleled RLC circuit proposed. An analytical method further developed calculate parameters proposed equivalent circuit, enables predict time-domain response MV A digital twin double-pulse-test setup LTspice, where simulated currents show good agreements with experimental measurements.
