Electrical Phenomena on Fully Airborne Vertical Electric Antennas in Extreme Weather Conditions

This is a conference extension of the paper ‘Investigation on mature storm cloud’s electric field using long airborne antennas’. The use vertical antennas (including VEDs—Vertical Electric Dipoles), lifted up by aerostats to high altitudes without being anchored ground, presents numerous advantages in comparison with large terrestrial VLF (Very Low Frequency) antenna structures. A slow-moving floating-earth conductor—a wire antenna—is subjected intense electrification mechanisms atmosphere and inside cloud layers, producing additional risks for transmitter flight train itself. electrical potential achieved this process is, therefore, compared flashover voltages over antenna’s upper fixing point, defining voltage margins at which able operate. processes are also model based experimental data occurrence corona discharges long, traversing layer. external strength (around wire) calculated older clouds various locations, showing correctness proposed analytical model, and, expanding it loss charge via corona.
