Was watching a show where maintenance was performed on a live HV line by way of a helicopter. The tech held a rod near the line which created an arc. I believe the arc was extinguished when the rod finally touched the line. Next it looked like they had replaced the tip of the rod with a donut shaped clamp that secured the helicopter to the line while maintenance was performed.
Assuming that the helicopter and line are initially at different potentials. Wondering how the potential is equalized between the helicopter and line? Heard it mentioned somewhere that it's the capacitance of the helicopter but I don't understand that.
