Bipolar dc corona is known to be a strong function of conductor voltage but little has been known about the influence of load current on bipolar corona. To evaluate the influence of load current, a bipolar cylindrical corona cage was constructed and operated with simulated dc load current flowing in the conductors. Measurements of load current, corona current, ion-current density, and conductor temperature showed that corona conductance was a function of load current. The dependence on load current was via temperature rather than magnetic field.
