“…To calculate the electromagnetic fields generated by return strokes, it is necessary to know the spatial and temporal variation of the return-stroke current along the channel [26]. Furthermore, the important parameter of the return stroke such as stroke per flash (multiplicity), stroke average (average in stroke per flash), time intervals (separation time between two strokes) are useful for the setting of relay protection pick-up in the circuit breaker system [27], [28]. [27] urged for the crucial of having multiple sequential of the impulse current test for any protective device (metal oxide varistor or circuit breaker) since typically lightning events produce multiple lightning strokes in nature.…”

The separation duration of Preliminary Breakdown (PB) to the First Return Stroke (PB-RS duration) and the ratio between the highest amplitude pulse of negative CG flashesand the first Return Stroke pulse (PB/RS ratio) were successfully used as a tool by many researchers to determine the relationship between lightning ground flashes and physical changes (latitude, regional and thunderstorm). Malaysia is one of the countries with the highest lightning flash density globally, and the occurrences of ground flashes are mainly due to monsoon seasons. Monsoons in Malaysia are Northeast, Southwest, and two transition periods. However, there is no available information to relate the lightning activities in Malaysia under the influence of all monsoon seasons. The above statements motivated our team to present a new statistical analysis of lightning flashes under two seasons' effects (Northeast and Southwest). 83 out of 332 electric radiation field data (fast fields) from six thunderstorms were selected and analyzed. The data recorded were using a 12-bit high-speed transient recorder (HDO 4024) with a resolution of tens of nanoseconds and sampling of 12.5 MS/s. PB/RS ratio between the monsoons is similar to each other. The PB-RS separation has two factors longer during the Southwest monsoon than during the Northeast monsoon. We classified the PB/RS ratio into four categories (>100%, 50-100%, 20-50%, and < 20%) as an indication of the preliminary breakdown strength. It found that the weakest pulse train (PB/RS ratio less than 20%) has shown a longer duration of PB-RS and produces higher lightning return strokes in a negative ground flash than the strong one. The results of this study could be evident that the lower strength of preliminary breakdown correlates to a lower Low Positive Charge Region (LPCR), which means the initial breakdown process only requires low energy to break the LPCR. Hence, these features have shown the highest number of stroke counts compared to pronounced ones. However, it would be more remarkable if one could provide bulky data for this specific study.

“…Contrarily, researchers have proposed the use of the distance protection of the relay pick-up time, and the times of lightning stroke measured by lightning location system (LLS) in order to determine the lightning stroke location [44]. Thus, after lightning hits on the transmission line by using its pick-up disturbance detection time is determined.…”

“…Other cases demonstrating that electric power is susceptible to lightning phenomenon occurred in the southeastern Amazonia in the state of Pará, where frequent outages have been attributed to this phenomenon. Thus, different outages have been produced in the Brazilian network [5,6]. This zone has the highest flash peak current magnitude compared to anywhere else worldwide [7,8].…”
