                         high-speed footage was recorded using Phantom v310 and v7.1 
                         (15,000 fps and 5,000 fps respectively) cameras. A total of 34 
                         negative strokes and 3 positive strokes were analysed. The 
                         recorded negative strokes presented an average peak intensity of 
                         8.0 V/m, 0 - 100 % rise time of 3.3 Ás, 10 - 90 % rise time of 1.8 
                         Ás and pulse duration of 6.4 Ás. The positive strokes presented an 
                         average peak intensity of 36.7 V/m, 0 - 100 % rise time of 22.9 
                         Ás, 10 - 90 % rise time of 7.4 Ás and pulse duration of 33.4 Ás.

                         high-speed videos, was 6.3 ms for the negative strokes and 81.5 ms
