Test Item

Surge withstand capability

Surge life test

In the glass tube ends in 8/20 us surge tester, applying the model that

corresponds to the impact resistance current, time interval for the

60 s of plus or minus the test 5 times. Test the dc voltage,

insulation resistance, static capacitance and check the appearance.

Apply 10KV voltage charged in 1500pF condenser and

apply the current to the specimen,200 times at 10

seconds of intervals.
