Abstract Properties of positive and negative leaders developing in air gaps ranging from 4 to
10 m that were subjected to 100/7,500‐μs voltage impulses were examined using a two …

Complete evolution of a lightning discharge, from its initiation at an altitude of about 4 km to
its ground attachment, was optically observed for the first time at the Lightning Observatory …

Since a large number of spherical shielding balls are adopted in valve hall, investigating
discharge characteristics of sphere-plane gap is of great significance for insulation design in …

Experiments on the breakdown characteristics of a long air gap containing a floating
conductor under switching impulse are carried out to address issues in live-line work …

Long air gaps containing a floating conductor are common in transmission and substation
projects. As the floating electrode moved across the gap, the lowest breakdown voltage area …

Live working is an important means for the maintenance of transmission lines. During the
process of entering the equipotential, the live working lineman is a floating conductor, which …

The streamer zone of positive leader during the breakthrough phase of long sparks was
experimentally investigated with two methods. One of the methods is the analysis of …

The numerical modeling of electrical discharges occurring in atmospheric air has been in
continuous development during the past decades in different fields, such as high-voltage …

Abstract Knowledge of leader corona is the basis for long spark discharge modelling, which
is critical to understand the underlying physics of lightning flashes and dielectric breakdown …

High‐speed video and electric field change data were used to analyze the initiation and
propagation of four predominantly vertical bidirectional leaders making connection to a …
