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 high dielectric ...
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 to assure quality ...
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 to remain lit ...
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 may, or may not, occur ...
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.
