Lightning discharge activity causes overvoltages in the electric power system, which may result in damage to the equipment and apparatus of the system. The lightning incidence is divided into two types: direct strikes and side strikes [1–4]. Direct strikes are lightning discharges that directly hit the line, structure or equipment, resulting in overvoltages of higher amplitudes. However, they are less common than side strikes, which are discharges that occur near the electric system and induce overvoltages of lower amplitudes than direct strikes, but may also cause damage in the distribution network. In this way, many works have evaluated the effect of side strikes on the insulation of electric power system equipment [5–8].

考虑标准和非标准脉冲形状的中压开关和熔断器的雷击耐受性

雷电放电活动会导致电力系统中出现过电压，这可能会损坏系统的设备和装置。雷击分为直击和侧击两种类型[1-4]。直接雷击是直接击中线路、结构或设备的闪电放电，导致更高幅度的过电压。然而，它们不如侧击常见，侧击是发生在电力系统附近的放电，产生的过电压幅度低于直接击中的幅度，但也可能对配电网络造成损坏。通过这种方式，许多工作已经评估了侧击对电力系统设备绝缘的影响[5-8]。
