The electrical breakdown of an insulator due to excessive voltage can occur in one of two ways: A puncture arc is a breakdown and conduction of the material of the insulator, causing an electric arc through the interior of the insulator. The heat resulting from the arc usually damages the insulator irreparably.
Breakdown voltage is a characteristic of an insulator that defines the maximum voltage difference that can be applied across the material before the insulator conducts. In solid insulating materials, this usually [citation needed] creates a weakened path within the material by creating permanent molecular or physical changes by the sudden current.
Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.
Insulator (electricity), a substance that resists electricity Pin insulator, a device that isolates a wire from a physical support such as a pin on a utility pole; Strain insulator, a device that is designed to work in mechanical tension to withstand the pull of a suspended electrical wire or cable; Mott insulator, a type of electrical insulator
Insulator (electricity), the use of material to resist the electric current and magnetism Insulating link, a device used on the hook of a crane; Insulation system, for wires used in generators, electric motors, transformers; Myelination, electrical insulation of nerve cells
In practice, for radio antennas, guy-wires, overhead power lines and most other loads, the strain insulator is usually in physical tension. [1] When the line voltage requires more insulation than a single insulator can supply, strain insulators are used in series: A set of insulators are connected to each other using special hardware. The ...
influence quantity In the field of power electronics any quantity generally external to a power supply which may affect its performance. inherent delay angle The current delay angle occurring, even without phase control, caused by multiple overlap. [q] inherent direct voltage regulation
Electrical insulation papers are paper types that are used as electrical insulation in many applications due to pure cellulose having outstanding electrical properties. Cellulose is a good insulator and is also polar , having a dielectric constant significantly greater than one. [ 1 ]
