Study on the Low Impedance Discharge Time Delay and Its Influence Factors in The Discharge Process of Shunt Capacitor and Discharge Core

In order to attain the low impedance discharge time delay and its influence factors of shunt capacitor and discharge core, the discharge waveform is researched. The influences of discharge voltage, capacitance and resistance value on low impedance discharge time delay is grasped by test. It is indicated that the circuit is in low impedance discharge when the discharge current growth rate climbed to the peak value in extreme short time. The low impedance discharge time delay will decrease when discharge voltage rises, and the low impedance discharge time delay is stable when capacitance or resistance value changing.
