Generating high voltages with a plasma coil transformer
A novel prototype plasma coil based dry-type transformer has been built and used to create 75kV peak impulse voltages from a 40kVd.c. capacitor bank. This device uses an air-cored coil of exploding wire to produce a high voltage output from a copper magnet wire winding. Effective insulation coordination has been developed for the unique requirements of this device. Preliminary theories behind the mechanisms which drive this device are presented. Future improvements are noted, which are planned to allow voltages of several hundred kilovolts to be generated.
