Dielectric, английский

- An insulating (nonconductive) material.
- A non-conductive insulator material between the center conductor and shield of coaxial cable. the dielectric constant determines the propagation velocity.
- A material that acts as an insulator.
Dielectric breakdown, английский

Dielectric breakdown voltage, английский
In an electrical insulating material, the voltage at which electrical breakdown occurs, i.e., the voltage at which current will flow and/or the material melts.
Dielectric coatings, английский
Thin-film coatings made of transparent dielectric materials, e.g. for laser mirrors or anti-reflection coatings
Dielectric connections, английский
Water connectors that reduce the flow of electricity related to galvanic corrosion, from the house piping to the water heater.
Dielectric constant, английский
- That property (k) of an insulating material which is the ratio of the parallel capacitance (c) of a given configuration of electrodes with the material as the dielectric, to the capacitance of the same electrode configuration with a vacuum as the dielectr
- Диэлектрическая проницаемость; диэлектрическая постоянная
- Measure of the ability of a dielectric material to store electrical potential energy under the influence of an electric field, measured by the ratio of the capacitance of a condenser with the material as the dielectric to its capacitance with a vacuum as the dielectric.

Dielectric strength, английский
- The voltage which an insulating material can withstand before breakdown occurs, usually expressed as a voltage gradient (such as volts per mil).
- A measure of the ability of an insulating material to withstand electric stress (voltage) without failure. fluids with high dielectric strength (usually expressed in volts or kilovolts) are good electrical insulators. (astm designation d 877.)
- The average voltage gradient at which electrical failure or breakdown occurs. expressed in volts per mil.
- The voltage gradient, expressed as kv/mm, that will cause a dielectric failure in an insulating material under very specific test conditions. dielectric strength does not imply that the insulator can withstand those potential gradients for an extended period of time.
- The extent to which a fluid can withstand electric voltage without failing. dielectric strength is measured as the minimum voltage at which an electric arc passing through a fluid causes fluid breakdown. high dielectric strength may indicate that a fluid is a good electrical insulator, while low dielectric strength might possibly signal that a fluid is contaminated with water.
- Measure of the insulating value of an electrical insulating medium. the value depends to some extent on the test method used.
Wavelength, английский
- Light is made up of electromagnetic waves; wavelength is the crest (peak)-to-crest distance between two adjacent waves.

Interference, английский
- Effect caused by the introduction of unwanted electrical signals into an electrical circuit. in cctv this results in "noise" in the signal or picture, which disrupts the picture.
