Sparking or 'flashing over' caused by a breakdown of
electrical insulation.
An insulated product exhibits the basic characteristics of a
capacitor.
causes a current to flow as the capacitor charges. This
current instantaneously rises to a high value as voltage is
applied then exponentially decays to zero as the DUT
becomes fully charged.
much faster than dielectric absorption.
The ratio between the voltage at which breakdown of the
insulating material occurs and the distance between the two
points subject to the applied voltage.
The physical phenomenon in which insulation appears to
absorb and retain an electrical charge slowly over time.
Apply a voltage to a capacitor for an extended period of
time, then quickly discharge it to zero voltage. Leave the
capacitor open circuited for a period of time then connect a
voltmeter to it and measure the residual voltage.
residual voltage is caused by the dielectric absorption of
the capacitor.
