A model of preliminary breakdown pulse peak currents and their relation to the observed electric field pulses

open access: yesGeophysical Research Letters, 2017
AbstractPreliminary breakdown pulses (PBPs) occur in the initial phase of lightning. A realistic model for their description is employed to investigate relation between PBP peak currents and PBP electric field amplitudes and their relation to the return stroke (RS) peak currents.

Impulse-driven surface breakdown data : a Weibull statistical analysis [PDF]

open access: yes, 2012
Surface breakdown of oil-immersed solids chosen to insulate high-voltage, pulsed-power systems is a problem that can lead to catastrophic failure. Statistical analysis of the breakdown voltages, or times, associated with such liquid-solid interfaces can ...

A 3D Interferometer-Type Lightning Mapping Array for Observation of Winter Lightning in Japan

open access: yesRemote Sensing, 2023
We have developed and deployed a 3D Interferometer-type Lightning Mapping Array (InLMA) for observing winter lightning in Japan. InLMA consists of three broadband interferometers installed at three stations with a distance from 3 to 5 km.

Refinement of the EC stray radiation estimates for ITER [PDF]

open access: yesEPJ Web of Conferences, 2023
The ITER ECRH&CD system is composed by 24 gyrotrons at 170 GHz that will deliver 20 MW at the plasma. Up to 6.7 MW will be injected in the empty vacuum vessel at the beginning of each plasma discharge to provide the gas breakdown.

Comparing the Wave Characteristics of Breakdown Pulses of the Lightning Waveforms in the Himalayan Region

open access: yesThe Scientific World Journal, 2021
We have analyzed the breakdown pulse train with or without the main event in this paper. Among the selected 81 flashes, 36 flashes are starting positively, and 45 are starting negatively.

Karakteristik Preliminary Breakdown Petir Downward Leader Sebelum Sambaran Negatif Pertama

open access: yesJurnal Nasional Teknik Elektro, 2014
A hundred lightning flash was observed in Padang city, West Sumatera at January until Mei 2013. The lightning that use to analyze is proceeding with preliminary breakdown pulse (PBP) train and followed by first negative return stroke (RS).

Characterization of Preliminary Breakdown Pulse Trains in Negative Cloud-To-Ground Flashes Recorded during A Rainy Season in The Bogota Savannah, Colombia

open access: yesTecnoLógicas, 2022
Lightning-generated electric field measurement is used to characterize cloud-to-ground (CG) flashes. Prior to the first return stroke (FRS), these signals sometimes exhibit a pulse train, known as preliminary breakdown pulses (PBP), whose study provides ...
