The use of helicopters as platforms equipped with infrared and UV detection, digital cameras and other inspection equipment is an effective method of increasing the efficiency and effectiveness of transmission line inspection. However, as a 'floating-potential conductor' near to a high-voltage transmission line, a helicopter causes distortion of the local electric field, with regions of high electric field near the helicopter's surface where the curvature is high. In this paper, these fields are investigated both by calculation and experimentally, using a simple metal sphere, and then a model of a helicopter, placed near to a short length of energized transmission line conductor.
► The paper studies the influence of floating-potential Conductors on the Field. ► The value of field is proportional to the excitation in the absence of corona. ► The effect of Conductors is negligible out of a distance equal to the diameter. ► Field near the surface of conductors doubled or increased more. ► Floating-potential is close to what is found at the center, without conductor.
