| Abstract | ||
| In this research pulse high voltage circuit was used including resistance, inductance and capacitor to achieve an experiment of cylindrically-tipped of plasma switch .The charging voltage of up to 9kV using Rogowski coil and current-shunt resistance (CVR) used to measure pulsed electrical discharge (PED). The current in both self-triggering and third-electrode triggering modes. The pulsed current peaks 4kA and the duration of circuit pulses were recorded between 0.1μs and 0.3μs. The experimental results has shown clearly the inductance effect in the circuit parts in under damped oscillation regarding the value of circuit parts in addition to the distance of the spark gap cylindrically-tipped electrodes during the plasma propagates under air pressure with their circuit impedance. Under the range of experimental states (2-30)Ω nominal impedance ranges were recorded, rely on the gap and circuit parameters. | ||
