Capacitors
Conductor
Electrical equipment; Capacitors
An electrical path which offers comparatively little resistance. A wire or combination of wires not insulated from one another, suitable for carrying a single electric current.
Corona
Electrical equipment; Capacitors
A luminous discharge due to ionisation of the gas surrounding a conductor around which exists a voltage gradient exceeding a certain critical value. A type of discharge--sometimes visible--in the ...
Corona resistance
Electrical equipment; Capacitors
The time that insulation will withstand a specified level field-intensified ionisation that does not result in the immediate complete breakdown of the insulation.
Coulomb
Electrical equipment; Capacitors
A unit of electric charge. It is named after Charles-Augustin de Coulomb. 1 coulomb is the amount of electric charge transported by a current of 1 ampere in 1 second. It can also be defined in terms ...
Breakdown (puncture)
Electrical equipment; Capacitors
A disruptive discharge through insulation. If plain dielectric films are used, this is usually catastrophic. If metallized films are used, self-healing should maintain the capacitor's integrity.
Breakdown voltage
Electrical equipment; Capacitors
The voltage at which the insulation between two conductors will break down. This voltage should be at least 50% ~ 100% greater than the capacitor's rated voltage.
Burn-in-test
Electrical equipment; Capacitors
Test designed to simulate conditions a product would encounter in actual operation. To shorten the duration of the test, it is conducted at maximum temperature and greater than rated voltage.
