A hot stick testing apparatus and method including a pair of generally ring-shaped electrodes spaced from one another at a predetermined distance. Each electrode has a central opening configured to receive the diameter of a hot stick under test positioned longitudinally through the central opening of both electrodes. Each electrode includes relatively smooth, outer surfaces presenting generally curved contours to enhance generating a relatively high electrical field intensity between the electrodes, without causing electrical flashover or arcing in the air gap between the electrodes. One of the electrodes is operatively connected to a source of high voltage and the other to ground. The testing apparatus has the ability to generate an electrical field intensity between the electrodes of about 140 to 170 kv per centimeter with an applied voltage in the range of 60 to 80 kv to the energized electrode.
