Spark gap - Wikipedia
A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the potential difference between the conductors exceeds the breakdown voltage of the gas within the gap, a spark forms, ionizing the gas and ...

The whole initial discharge process in gas spark gap was simulated in this paper by PIC-DSMC code. The evolutions of electron density distribution and ion density distribution were obtained, the electric field distribution in the gap was analyzed, and the process from electron emission to plasma channel was presented.
What is a spark gap, and why we need it on a PCB? - Page 1
2014年10月31日 · The newest term usage of Spark gap for the PCB sacrificial break over gaps is amusing. It uses the arc gap concept with no stabilizing medium nor physical contractors. It is extremely low duty, contaminate medium (free air makes it not calibrated), very low repeatability (well into the sacrificial rating range).
Electrical sparks (Fig. 10.2 illustrates different types of spark generator) are defined as discontinuous electrical discharges across a gap between at least two electrodes constituting the analytical gap (spark gap). The discharge current is supplied by a cyclically charged capacitor C.
Electric spark - Wikipedia
An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
Experimental study on electrostatic spark discharge under …
2023年4月1日 · In this study, the characteristic of spark discharge is systematically studied. When the electric field strength exceeds the breakdown strength of the gas in the electrode gap, spark discharge will be generated. Spark voltage drops rapidly and spark current rises rapidly. The power surges to a peak value.
Evaluation of spark discharge - ScienceDirect
2020年9月1日 · The effects of the energy (capacitance, voltage) and electrode parameters (electrode gap, electrode shape and electrode material) on the characteristics of electric spark discharge are studied experimentally and computationally.
Spark gap technology has evolved where the atmosphere or gas between the two electrodes was confined in a container so that the external atmosphere did not affect its arcing performance.
What is spark gap and how does it work - Electrotopic.com
A spark gap is a device used to produce an electrical discharge (spark) between two electrodes separated by a small gap filled with a non-conductive gas or air. Its primary function is to allow high voltage pulses to pass through when a certain threshold voltage is reached, at which point the insulating properties of the gas break down and ...
Gas tubes (gas filled spark gaps) are basically high energy voltage controlled switching devices. They are unique in their ability to repeatedly switch currents of thousands of amperes, which leads to their most common usage as transient protectors for applications where high energy transient electrical surges are anticipated.
