Voltage
Insulation Resistance
Test Condition / Description
The voltage is measured with a slowly rate of rise dv / dt=100V/s
The maximum impulse spark-over voltage is measured with a rise time of
dv / dt=100V//μs or 1KV/μs
The resistance of gas tube shall be measured each terminal each other terminal,
please see above spec.
The capacitance of gas tube shall be measured each terminal to each other
terminal.
Test frequency :1MHz
The maximum current applying a waveform of 8/20μs 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.

Cautions and warnings
u
u
u
u
Gas discharge tubes (GDT) must not be operated directly in power supply networks.
Gas discharge tubes (GDT) may become hot in case of longer periods of current stress (danger of burning).
Gas discharge tubes (GDT) may be used only within their specified values. In the event of overload, the head contacts may
fail or the component may be destroyed.
Damaged Gas discharge tubes (GDT) must not be re-used.
