Test Condition / Description

Requirement

DC Spark-over Voltage

The voltage is measured with a slowly rate of rise dv / dt=100V/s

Impulse Spark-over

Voltage

The maximum impulse spark-over voltage is measured with a rise time of

dv / dt=100V//

μs or 1KV/μs

Insulation Resistance

The resistance of gas tube shall be measured each terminal each other terminal,

please see above spec.

Capacitance

The capacitance of gas tube shall be measured each terminal to each other

terminal.

Test frequency :1MHz

Nominal Impulse

Discharge Current

The maximum current applying a waveform of 8/20

μs that can be applied across

the terminals of the gas tube. One hour after the test is completed, re-testing of the

DC spark-over voltage does not exceed

±30% of the nominal DC spark-over

voltage. Dwell time between pulses is 3 minutes.

Nominal Alternating

Discharge Current

Rated RMS value of AC current at 50Hz, 1 sec. 10 times. Intervals: 3min. The DC

spark-over voltage does not exceed

±30% of the nominal DC spark-over voltage.

IR > 10
