Impulse Voltage
Each individual capacitor should be subjected to a 5kV (Type
KX: 8kV) impulses for three times. After the capacitors are
applied to life test.
Apply a voltage of 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 weight and then a
90° bend, at the point of egress, in one direction, return to
original position, and then apply a 90° bend 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 cheese-cloth. 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.
