The trigger transformer circuit must  
be capable of providing a small sus-  
taining current, typically, a few tens  
of milliamperes for reliable triggering.  
the characteristic “ring down” of con-  
duction current is used to compute  
circuit impedance. The circuit is  
mechanically designed to yield the  
lowest possible overall inductance  
and resistance. Excluding the CVR,  
a typical circuit resistance is 60  
milliohms. Circuit inductance can  
vary from 30 to 50 nH.  
Life test data indicate reliable firing on  
many gaps after 2000 shots at 6000  
amps peak current for 200 ns pulse  
width at 3.5 kV and load of 0.25  
ohm. Life will be reduced with higher  
peak currents.  
Life  
End of life is determined by changes  
in the gaps performance due to elec-  
trode erosion or gas cleanup. Prefire  
(firing without a trigger signal) or fail-  
ure to fire (no fire with trigger applied)  
are typical symptoms determining  
end of life.

For the GP-486 the operating range  
(E-E) is 2.0 to 4.0 kV with a minimum  
trigger voltage (VT(OC)) open circuit  
of 2.0 kV. Static Breakdown Voltage  
(SBV) is 4.5 kV. Trigger mode is "C" -  
positive trigger and positive opposite  
electrode (OE). Changing polarities  
will result in changes in operating  
characteristics. The triggered spark  
gap operating range is shown in  
Figure 3.
