The dielectric withstanding voltage test (also called high-potential, over-potential voltage-breakdown, or dielectric-strength test) consists of the application of a voltage significantly higher than rated voltage for a specific time, between mutually insulated portions of a component part or between insulated portions and ground.
As the dielectric constant increases, the electric flux density increases, if all other factors remain unchanged. This enables objects of a given size, such as sets of metal plates, to hold their electric charge for long periods of time, and/or to hold large quantities of charge. Materials with high dielectric constants are useful in the manufacture of high-value capacitors. A high dielectric constant, in and of itself, is not necessarily desirable.
