Spark-over Voltage
Test Condition / Description
The voltage is measured with a low rate of rise dv / dt=100V/s
The maximum impulse breakdown voltage is measured with a rise time of
dv / dt=1000V/ s
The maximum current applying a waveform of 8/20 s that can be applied
across the terminals of the gas tube without causing the gas tube to
change more than ±25% from its initial measured DC breakdown voltage.
Dwell time between pulses is 3 minutes.
