Electric Stress Control

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 in the region, and ε0 is the electric permittivity of free space (vacuum). However, in most of the high voltage apparatus, space charges are not normally […]

What is Current

What is Current: What is Current – There are free electrons available in all semiconductive and conductive materials. These free electrons move at random in all directions within the structure in the absence of external pressure or voltage. If a certain amount of voltage is applied across the material, all the free electrons move in […]
