Figure 1, 6.4 μS Short Circuit Current Waveform, Test Configuration 1.
6.4 μS pulse into a Type 9127-1 Injection probe.
Measuring the short circuit current across a Non-inductive 0.1 ohm resistor. 4000 A?
NOTE
This would be an error because of the inductive reactance, A curve measuring the reactance at 1
MHz (1 μS) would measure 1 ohm so the correct current would be 400 volts divided by 1 ohm or
400 A.
Figure 2, 6.4 μS Short Circuit Current Waveform, Test Configuration 1.
6.4 μS pulse into port 2 (2:1) of Type 9335-2 Injection probe. Measuring the short circuit
current across a Non-inductive 0.1 ohm resistor. 4000 A?
Figure 3, 70 μS Short Circuit Current Waveform, Test Configuration 2.
70 μS into a Type 6220-4 Isolation transformer into port 2 of the Type 9335-2 Injection
probe. Measuring the short circuit current across a Non-inductive 0.1 ohm resistor. 100
A.
Figure 4, Short Circuit Current Waveform, Test Configuration 1.
70 μS into two Type 9335-2 injection probes with 4 turns for the primary. Measuring the
short circuit current across a Non-inductive .05 ohm resistor. 400 A. (this seems to be
equivalent to Test Configuration 2).

70 μS into two Type 6220-4 into the 4:1 port of the Type 9616-1 injection probes.
Measuring the short circuit current across a Non-inductive .1 ohm resistor. 800 A.
