What is Electric field stress?
An Electric field stress depends on the mechanical strength of the materials and the stresses that are generated during their operation. During high voltage applications, the dielectric strength of insulating materials are developed when subjected to high voltages.
What happens when dielectric breakdown occurs?
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
What is the material use in the capacitor?
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
Is dielectric strength the same as dielectric constant?
No, these are two unrelated properties of a material.
Define methods of stress control in high voltage cables?
A method of stress control is controlling the distribution of dielectric stress. Uniform distribution of dielectric stress may be achieved in high voltage cables by surrounding the high stress areas of the high voltage cable with a tube of high permittivity material that makes contact at one end with a ground electrode contacting the shield of the high voltage cable.
What is dielectric strength?
Dielectric strength is a measure of the ability of an insulating material to withstand electric field stress without breaking down or becoming conductive. It is typically measured in volts per unit thickness of the material. A higher dielectric strength indicates a better insulating material.
