Abstract This study assesses the reliability and limitations of the Geostationary Lightning Mapper (GLM) in detecting continuing currents by comparing observations from ground‐based high‐speed cameras with GLM‐16 data. Our findings show that th

The Influence of Diethylaniline and Toluene on the Streamer Propagation in Cyclohexane between a Point-Plane Gap under Positive Impulse Voltage Stress
Autor: Carl P. Wolmarans, Cuthbert Nyamupangedengu, Carina Schumann, Neil J. Coville, Marcelo M. F. Saba
Publikováno v: Energies, Vol 15, Iss 13, p 4861 (2022)
Liquid insulation is used in high voltage equipment such as power transformers as both dielectric medium and coolant. Breakdown in liquid insulation tends to be governed either by streamer initiation under more uniform fields, or by streamer propagat

Scientific Reports
Upward lightning studies took place in Rapid City, South Dakota, USA and S. Paulo, Brazil during the summer thunderstorm seasons from 2011 to 2016. One of the main objectives of these campaigns was to evaluate and characterize the triggering of upwar

Autor: H.G.P. Hunt, D. R. Poelman, Lukas Schwalt, Christian Vergeiner, Marcelo M. F. Saba, Wolfgang Schulz, Carlos T. Mata, Dustin Hill, Carina Schumann, Tom A. Warner, Stéphane Pedeboy
Publikováno v: Natural Hazards and Earth System Sciences, Vol 21, Pp 1909-1919 (2021)
Information about lightning properties is important in order to advance the current understanding of lightning, whereby the characteristics of ground strike points (GSPs) are in particular helpful to improving the risk estimation for lightning protec
