KEMAMPUAN ARRESTER SEBAGAI PENGAMAN TRANSFORMATOR [PDF]
, 2021 Electrical interference at the substation might be caused by several internal and external factors. The interference that were often had was the interference caused by nature, namely lightning which caused overvoltage.

Exploring terrestrial lightning parameterisations for exoplanets and brown dwarfs [PDF]
Planetary & Space Science, 204 (2021), 105247, 2021 Observations and models suggest that the conditions to develop lightning may be present in cloud-forming extrasolar planetary and brown dwarf atmospheres. Whether lightning on these objects is similar to or very different from what is known from the Solar System awaits answering as lightning from extrasolar objects has not been detected yet. We explore

Upward Lightning at the Gaisberg Tower: Initiation Mechanism and Flash Type and the Atmospheric Influence [PDF]
, 2022 Upward lightning is much rarer than downward lightning and requires tall ($100+$~m) structures to initiate. It may be either triggered by other lightning discharges or completely self-initiated. While conventional lightning location systems reliably detect downward lightning, they miss a specific flash type of upward lightning that consists only of a ...

Could macroscopic dark matter (macros) give rise to mini-lightning flashes out of a blue sky without clouds? [PDF]
Atmosphere 2021, 12, 1230, 2021 A recent study pointed out that macroscopic dark matter (macros) traversing through the earth's atmosphere can give rise to hot and ionized channels similar to those associated with lightning leaders. The authors of the study investigated the possibility that when such channels created by macros pass through a thundercloud, lightning leaders may locked

Theory of ball lightning [PDF]
Sci. Rep. 6, 28263 (2016), 2014 We present a comprehensive theory on the formation of ball lightning, a luminous sphere sometimes observed after normal lightning. In a ball lightning event, a relativistic electron bunch can be produced by the stepped leader of lightning and coherently emit high-power microwave when striking the ground.
