Test Condition/Description
The voltage is measured with voltage ramp dv/dt=100V/s.
The maximum impulse spark-over voltage is measured with voltage ramp
dv/dt=1000V/μs.
The resistance of gas tube shall be measured between two electrodes.
The capacitance of gas tube shall be measured between two electrodes.
Test frequency: 1MHz
Maximum 8/20μs surge current that can be applied between two electrodes,
5 positive and 5 negative surges, with 3 minutes interval time, without
causing the DC spark-over voltage to change more than 25% from its initial
value.
The maximum 10/700μs surge that can be applied to the Gas Tube, 5
positive and 5 negative surges, with 1 minute interval time, without causing
the DC spark-over voltage to change more than 25% from its initial value.
