FIG. 1.

An electrical schematic of the three-stage Marx generator energy supply. The charging circuit was a 230 V to 80 kV step-up transformer, 100 kΩ current limiting resistor, and 360 kV diode. Circuit values: C 1, C 2, and C 3 = 5.7 μF, R = 30 kΩ, Rd  = 100 kΩ.

FIG. 2.

(Color online) A 60 m long arc outside the University of Canterbury High Voltage Laboratory, produced using a 270 kV impulse applied to a 0.2 mm diameter enameled copper wire.

FIG. 3.

The dwell time of the plasma bead restrike mechanism is correlated to the AEF at the time of plasma bead formation, E 1. The data from experiments that did not produce restrike have been shown with an arbitrary dwell time in this figure. The datum that was used to determine kE is indicated with a circle.

Image of FIG. 4.
FIG. 4.

The energy dissipated during the first current pulse, W 1, is correlated with the wire’s length, (R 2 = 0.95). Results from two- and three-stage energy supply configurations are shown. Only the experiments that produced restrike were used to derive the linear fit.

FIG. 5.

Capability diagrams for the Marx generator used in this work, shown in one-, two-, and three-stage configurations.

Tables

Table I.

A selection of commercially available impulse generators, their specifications, and the estimated maximum restrike length that they could produce.
