- Overvoltage events may cause the electric field to exceed the dielectric strength of air and result in the formation of an plasma of the arc.
- For instance, the dielectric strength of silicon dioxide films of a few hundred nm to a few ?m thick is approximately 0.5GV / m.
- It must therefore have high dielectric strength, thermal conductivity, and chemical stability, and must keep these properties when held at high temperatures for extended periods.
- They occur when the electric field at the conductor exceeds the dielectric strength of the air, the " disruptive potential gradient ", roughly 30 kilovolts per centimeter.
- Impurities, tiny mechanical damages, or imperfections in the dielectric can affect the structure, changing it from amorphous to crystalline structure and thus lowering the dielectric strength.
- The dielectric films, depending on the desired dielectric strength, are drawn in a special process to an extremely thin thickness, and are then provided with electrodes.
- Plastic film capacitors were significantly smaller in physical size ( better volumetric efficiency ), with the same capacitance value and the same dielectric strength as comparable paper capacitors.
- Because of the smaller relative permittivity and lower dielectric strength of the PEN polymer, PEN film capacitors are physically larger for a given capacitance and rated voltage value.
- Because dielectric materials usually contain minute defects, the practical dielectric strength will be a fraction of the intrinsic dielectric strength of an ideal, defect-free, material.
- Because dielectric materials usually contain minute defects, the practical dielectric strength will be a fraction of the intrinsic dielectric strength of an ideal, defect-free, material.
- The voltage at which the dielectric becomes conductive is called the breakdown voltage, and is given by the product of the dielectric strength and the separation between the electrodes.
- Typical AC power entry modules often have dielectric strengths of 2000 volts or more, and can handle currents of up to 10 to 20 amperes at 250 volts maximum.
- The insulating quality or dielectric strength and breakdown voltage of the insulators as well as the geometry determine the maximum voltage and current produced for a given speed of rotation.
- In presence of chloride ions, the precipitated material is atacamite; its semiconductive properties lead to increased current leakage, deteriorated dielectric strength, and short circuits between traces.
- Electrolytic capacitors feature unlimited charge / discharge cycles, high dielectric strength ( up to 550 V ) and good frequency response as AC resistance in the lower frequency range.
- With this very thin dielectric oxide layer, combined with a sufficiently high dielectric strength, the niobium electrolytic capacitors can achieve a high volumetric capacitance comparable to tantalum capacitors.
- These films have much less tensile stress, but worse electrical properties ( resistivity 10 6 to 10 15 ?�cm, and dielectric strength 1 to 5 MV / cm ).
- Since the dielectric strength of gases varies depending on the shape and configuration of the electrodes, it is usually measured as a fraction of the dielectric strength of Nitrogen gas.
- Since the dielectric strength of gases varies depending on the shape and configuration of the electrodes, it is usually measured as a fraction of the dielectric strength of Nitrogen gas.
- Typical specifications are : flash point 140 �C or greater, pour point " 6 �C or lower, dielectric strength 24 MV / m ( RMS ) or greater.
