Test Condition/Description
DC Spark-over
Voltage
The voltage is measured with voltage ramp dv/dt=100V/s. Test is
between each side electrode and center electrode.
Maximum Impulse
Spark-over Voltage
The maximum impulse spark-over voltage is measured with voltage
ramp dv/dt=1000V/μs. Test is between each side electrode and
center electrode.
Requirement
Maximum surge current that can be applied through center electrode
with 8/20μs waveform, for 10 times with 3min interval time, which will
be equally divided between each side electrode to center electrode.
