Corona discharge – Corona effect Corona effect is in a uniform electric field, a gradual increase in the voltage across the gap causes the gap to break in the form of a spark without pre-discharge. On the other hand, if the electric field is not uniform, the increase in voltage causes a partial discharge of …
Dielectric voltage breakdown are here disscussed but if you need more basic details first visit these article. This aricle is about more advanced about time characterstics. Spark lag time lag In fact, especially in high voltage engineering, breakdown in the pulse field is very important. When a voltage is applied, even if the applied voltage …
Factors that affect the vacuum gap of breakdown voltage Ideally, a vacuum is the best insulator with a breakdown strength of about 104 kV / c. The breakdown voltage of a high vacuum is such that, with a small increase. The gap maintained at that voltage is destroy indefinitely. However, this definition is not always …

The breakdown mechanism of gases are explain with suitable diagrams. Also breakdown mechanism explain by pashchen law an explain clearly. Breakdown in electronegative gases The attachment of electrons to neutral molecules was not considere in the above analysis. Free electrons are remove by the attachment of electrons, which increases the dielectric strength of gas. The …
Breakdown mechanism are devide in to two mechanisms of gas decomposition are known. Also These are the mechanisms of avalanches and streamers. Electronic avalanche mechanism (Townsend destruction process) The Townsend decomposition mechanism is one of the processes considere in the decomposition process. It is based on the production of continuous secondary avalanches to produce faults.Also …
All types of gas ionization method are discuss below with example. Also pictures and sketches are present Ionization due to simple collision Ionization occur at the electron kinetic energy (1/2 mu²) that colliding with a neutral gas molecule exceeding the ionization energy (Ei = e Vi) of the molecule. (That is, when mu²> Ei) M …
Gas ionization Gas ionization process is disscuss in this article with examples. An electrically insulating material (or dielectric) is a material that can hold an electrostatic field almost indefinitely. Therefore, these materials are very resistant to the passage of direct current. However, it cannot withstand an infinitely high voltage. If the voltage applied to the …
Insulating gases types Electronegative Insulating gases are good insulators because ions quickly combine with ions generated in the spark. However, they tend to be caustic. However, some gases only dissociate where the discharge is (or wants to be), which makes them particularly good insulators. Gases with electronegative species (i.e. halogens such as chlorine) are good …
The main concept of any insulator is to disassemble the electrical conductivity of the high voltage power transmission or distribution line from the transmission or distribution tower. Insulators are the main component of the transmission line and there are three main types of insulators that are use for air insulators such as. Pin Insulator Suspension …
