Electrical equipment > Capacitors

moisture resistance

Electrical equipment; Capacitors

The ability of a material to resist absorbing moisture from the air or when immersed in water

oil capacitors (self healing)

Electrical equipment; Capacitors

These are often used in high-power electronic equipment. An oil-filled capacitor is nothing more than a paper capacitor that is immersed in oil. Since oil impregnated paper has a ...

overvoltage

Electrical equipment; Capacitors

A voltage above the normal operating voltage of a device or circuit. In a dielectric withstand test, capacitors are overvoltage-tested (Hi-potted) at 1.5X or 2X its rated voltage ...

parallel lamp operation

Electrical equipment; Capacitors

Refers to ballasts that employ multiple-output current paths from a single ballast to allow lamps to operate independently of one another, allowing other lamps operated by ballast ...

partial discharge

Electrical equipment; Capacitors

A partial discharge is an electric discharge that only partially bridges the insulation betwen conductors when the voltage stress exceeds a critical value. Partial discharges ...

pcb (polychlorinated biphenyls)

Electrical equipment; Capacitors

Chemical pollutant formerly used in oil-filled capacitors which have been outlawed since the 1970's and are no longer used in the capacitor and transformer industries.
