“…Furthermore, Zhuang et al [109] used the results of LPM to improve EGM and redefined the attraction area of the ground wire and conductor to lightning: the centre of the circular attraction area is on the leader tip and the radius is the final jump distance, which takes the influence of the upward leader length on the lightning breakdown process into account.…”

Lightning and lightning induced effects have significant influence on many aspects affecting the public, which makes the research of lightning and lightning protection very important. However, due to the strong randomness and complex discharge mechanisms of lightning, the understanding of lightning is still far from satisfactory. On the basis of the International Conference on Lightning Protection 2014, this study gives a review of recent progress on lightning and lightning protection research covering the following aspects: lightning locating and observation, lightning physics, lightning electromagnetic transients, and lightning protection for various systems. The goals of this study are to give readers an overall introduction to the recent progress in lightning and lightning protection research, and to motivate them to conduct further studies to address the unsolved problems in lightning-related research.

“…Therefore, neglecting the upward leader by EGM leads to significant error in the results for SFR for high-voltage and ultrahigh-voltage structures. To overcome this situation, Zhuang et al modified the EGM in [18]. They considered the upward leader and its propagation angle in addition to the fundamentals of striking distance.…”

“…In [18], the formulation of modified EGM is obtained by numerical fitting of the results of the LPM for a sample 1000 kV tower. Afterwards, the effect of the tower height is considered in the formulations.…”

“…However, the LPM which the results are used for comparison neglects the space charge due to lightning's vertical movement, and zigzag movement of downward leader. Moreover, from [18], it can be concluded that the accuracy of the SFR estimated by the revised EGM decreased as the height of structures are changed.…”

“…Thus, engineers need a method which is both accurate and simple. Zhuang et al [18] included the upward leader inception and its propagation angle to EGM for SFR calculation. This new modified EGM incorporates the physics of lightning into SFR calculation; thus, yields estimations that are closer to the field data.…”
