ELECTRONIC PRINCIPLES - OD1647 - LESSON 1/TASK 1
The type of dielectric used and its thickness govern the amount
of voltage that can safely be applied to the electrolytic
capacitor. If the voltage applied to the capacitor is high
enough to cause the atoms of the dielectric material to become
ionized, arcing between the plates will occur. In most other
types of capacitors,. arcing will destroy the capacitor.
However, an electrolytic capacitor has the ability to be self
healing. If the arcing is small, the electrolytic will
regenerate itself. If the arcing is too large, the capacitor
will not selfheal and will become defective.
(5) Oil Capacitors. OIL CAPACITORS are often used in high
power electronic equipment. An oilfilled capacitor is nothing
more than a paper capacitor that is immersed in oil. Since oil
impregnated paper has a high dielectric constant, it can be used
