ELECTRICAL RATING
Item
DC Spark-over Voltage Maximum Impulse 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 8/20ȝs 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.
Requirement
Impulse Discharge Current To meet the specified value
Alternating Discharge Current
Rated RMS value of AC current at 50Hz, 1 sec. 10 times. Intervals: 3min. DC breakdown voltage may not change more than ±25% from its initial measured DC breakdown voltage. IR>1 08 ohms (-20%, +30% for 70 – 90V).
The resistance of gas tube shall be measured each terminal each other Insulation Resistance terminal.please see above spec Capacitance The capacitance of gas tube shall be measured each terminal to each other terminal. Test frequency :1MHz
