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// s or 1KV/ s 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 s 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 ohms.
