Observation of an upward lightning flash with 21 upward positive leaders initiated from different wind turbines in wind farm

High Voltage
As the wind turbine height increases, the probability of multiple upward leaders flashes within the wind farm increases. In this study, an upward lightning flash containing 21 upward positive leaders (UPLs) initiated from different wind turbines in ...

Differences in M‐components between triggered lightning striking the ground and overhead line

High Voltage
In the summer of 2018–2019, rocket‐triggered lightning experiments were conducted in Guangzhou, China. There were two types of lightning targets: ground and overhead line.

Thunderstorm total lightning activity behavior associated with transmission line trip events of power system

npj Climate and Atmospheric Science
High-voltage transmission lines are susceptible targets for lightning strikes. It is an interesting topic how the trip event of transmission line is related to the area, location, and intensity of thunderstorms occurring at that time and that place ...

Relationship between radar reflectivity thresholds and very low frequency/low frequency total lightning for thunderstorm identification

High Voltage
To improve our knowledge of the spatio‐temporal correspondence between radar reflectivity and VLF/LF total lightning data, this paper proposes indexes to quantify the horizontal distribution and temporal evolution characteristics between radar composite ...

Seasonal Influences on the Impulse Characteristics of Grounding Systems for Tropical Countries

Energies, 2019
One of the most important parameters of the performance of grounding systems is the soil resistivity. As generally known, the soil resistivity changes seasonally, hence the performance of grounding systems, at DC and under high impulse conditions.

Incompatibilism and the Principle of Sufficient Reason in Kant’s 'Nova Dilucidatio'

Journal of Modern Philosophy, 2022
The consensus is that in his 1755 'Nova Dilucidatio', Kant endorsed broadly Leibnizian compatibilism, then switched to a strongly incompatibilist position in the early 1760s.

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

High Voltage
Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed
