Der Beginn der öffentlichen Elektrizitätsversorgung kann weltweit um 1880 datiert werden.
Seither ist die Elektrizität einer der Hauptmotoren der industriellen Entwicklung und spielt …

Lightning discharges between charged clouds and the Earth's surface are responsible for
considerable damages and casualties. It is therefore important to develop better protection …

This paper presents current and electric field measurements from two triggered lightning
flashes, 9519 and 9516, initiated by the “classical” and “altitude” technique, respectively, at …

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 …

In this work, we represent the lightning initiation scenario as a sequence of two transitions of
discharge activity to progressively larger spatial scales: the first one is from small-scale …

In this paper, we observe the dynamic expansion process of positive leader channels under
impulses with different rise times in a 1-m air gap using a Mach-Zehnder interferometry and …

We present high‐speed video images (recorded at 300 kfps) of an upward positive leader
developing stepwise from the top of a grounded triggering wire. The leader initiated from the …

This paper reports on a laboratory experiment to study the effect of vehicle net charge on the
inception of a positive leader from an aircraft exposed to high atmospheric electric fields …

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 …

Narrow Bipolar Pulses are generated by bursts of electrical activity in the cloud and these
are referred to as Compact Intracloud Discharges (CID) or Narrow Bipolar Events in the …
