Investigating Spatial‐Temporal Optical Emission Spectroscopy of Unstable Positive Leaders in Long Sparks Under Atmospheric Pressure

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores exciting state species and reaction pathways in positive leaders to better understand the breakdown mechanisms of long air gap discharges and natural lightning. Emission spectra from an unstable positive leader in a 1 m rod‐plate air gap under switching impulse voltages were observed, spanning 300–800 nm.
