DC spark-over voltage
It is the static behavior of GDT. DC spark-over voltage is measured with 100V/s low voltage rate which ignites the GDT.
Max. Impulse breakdown voltage
It is the dynamic behavior of GDT. Impulse breakdown voltage is measured with dv/dt=100V/μs and 1KV/μs voltage rate
which ignites the GDT.
Max. Impulse discharge current
The maximum peak current defined at 8/20s current pulse which is allowed to be applied at least ten times without
causing DC spark-over voltage change more than a specific rate.
Impulse Life
The minimum number of 10/1000s (or 8/20s) current waveform impulse which is allowed to be applied without causing
DC spark-over voltage change more than a specific rate.
Nominal Alternating discharge current
The rated rms value of AC current flows through the GDT which tests at 50Hz, 1sec.
DC holdover voltage
This value is defined as the maximum DC voltage across the terminals of GDT which is expected to return its high
impedance state after the GDT breakdown.
Insulation Resistance
Insulation resistance value measures on the GDT's terminals under the specified DC voltage.
Capacitance
The capacitance of the GDT is measured at 1MHz.
