Computation of Corona Space Charge, Electric Field, and V-I Characteristic Using Equipotential Charge Shells

A charge simulation technique incorporating discretized equipotential charge shells in the volume is used to approximate the electric field and space charge around a single conductor in corona and to compute the voltage-current relationship for the discharge. No iteration is required in the solution method. Results are compared to corona in coaxial geometry, for which analytical treatment is also possible, and to experimental V-I measurements in line-to- plane geometry.
