Townsend Current Growth Equation: Referring to Fig. 2.1 shows the Townsend Current Growth Equation. let us assume that n0 electrons are emitted from the cathode. When one electron collides with a neutral…
Ionization Processes: A gas in its normal state is almost a perfect insulator. However, when a high voltage is applied between the two electrodes immersed in a gaseous medium, the…
Surge Diverter | Lightning Arrester Types: The earthing screen and ground wires can well protect the electrical system against direct lightning strokes but they fail to provide protection against travelling…
Oil Circuit Breaker Diagram: In such Oil Circuit Breaker Diagram, some insulating oil (e.g., transformer oil) is used as an arc quenching medium. The contacts are opened under oil and…
Circuit Breakers Definition: A circuit breaker can make or break a circuit either manually or automatically under all conditions viz., no-load, full-load and short-circuit conditions. This characteristic of the Circuit…
Boundary Element Method (BEM) in Electric Field: Though the charge simulation method is known for its accuracy and speed, it is not very efficient in case of multi-dielectric problems and…
Charge Simulation Method for Electric Field: Charge Simulation Method (CSM) belongs to the family of integral methods for calculation of electric fields. There are two variations of this method: CSM…
Electric Stress Control: The Electric Stress Control distribution is usually governed by the Poisson's equation: where φ is the potential at a given point, ρ is the space charge density…
