Impulse Voltage
Each individual capacitor should be subjected to a 5kV (Type
KX: 8kV) impulses for three times. Then the capacitors are
applied to life test.
Apply a voltage from Table 4 for 1000 hrs. at 125+2/-0 C, and
relative humidity of 50% max.
Post-treatment:
The capacitor should be subjected to applied flame for 15 sec.
and then removed for 15 sec. until 5 cycles are completed.
As shown in the figure at right, fix the body
of the capacitor and apply a tensile weight
gradually to each lead wire in the radial
direction of the capacitor up to 10N and keep
it for 10 1 sec.
Each lead wire should be subjected to 5N of weight and bent
90 at the point of egress, in one direction, then returned to its
original position and bent 90 in the opposite direction at the
rate of one bend in 2 to 3 sec.
The capacitor should be individually wrapped in at least one but
not more than two complete layers of cheesecloth. The
capacitor should be subjected to 20 discharges. The interval
between successive discharges should be 5 sec. The U
should be maintained for 2 min. after the last discharge.
