ABSTRACT:
An apparatus and method for detecting the presence of high conductivity or permittivity conditions in electrically insulating materials, including a first electrode and a second electrode for being placed in spaced-apart relation on an insulator to be tested for a high conductivity or permittivity condition, and a high voltage source for energizing the first electrode and second electrode at different potentials. At least one gas gap is positioned between the first electrode and the second electrode and proximate a surface of the insulator; and a detector determines the level of ionization of the at least one gas gap while the electrodes are energized.
