ELECTRICAL RATING Item DC Breakdown Test Condition / Description Requirement The voltage measured at a rise time of 100v/s. Voltage Maximum Impulse The maximum breakdown voltage at rise times of 100v/us and 1000v/us. Breakdown Voltage The maximum current applying a waveform of 8/20us that can be applied Maximum Impulse across the terminals of the gas tube without causing the gas tube to Discharge Current change more than ±25% from its initial measured DC breakdown voltage. Dwell time between pulses is 3 minutes. Rated RMS value of AC current at 50Hz, 1 sec. 10 times. Intervals: 3min. Alternating DC breakdown voltage may not change more than ±25% from its initial Discharge Current measured DC breakdown voltage. IR > 108 ohms (-20%, +30% for 70 – 90V). Impulse Life The minimum number of impulses of a specified waveform and peak current which a gas tube will conduct without causing the gas tube to change more than ±25% from its initial measured DC breakdown voltage. Dwell time between pulses is 1-2 minutes. DC Holdover Voltage The maximum DC voltage across the two terminals of the gas tube under which it may be expected to return to the high impedance state after the gas tube breakdown. The resistance of the gas tube shall be measured each terminal to each other terminal. DC Breakdown Voltage Measuring Voltage Insulation 70-150V 50V Resistance 151-400V 100V 470-1000V 250V 1001-2000V 500V 2001-6000V 1000V Capacitance The capacitance of a gas tube shall be measured each terminal to each other terminal. Test frequency: 1MHz In measurements involving 3-electrode gas tubes, the terminal not being tested shall be connected to a ground plane. To meet the specified value
