7.2.1 Open Circuit Voltage (OCV)
Figure 7-1 Open circuit voltage (OCV) [1]
Front time: T1 = 1,67 x T = 1,2µs ± 30%
Time to half value: T2 = 50µs ± 20%
Verification of the Surge output signal (HI and COM) in the front view can be done with the help
of the in capture 15.2.1 described PDP 8000.
7.2.2 Short Circuit Current (SCC)
Figure 7-2: Short circuit current (SCC) [1]
Front time: T1 = 1,25 x T = 8 µs ± 20%
Time to half value: T2 = 20 µs ± 20%
For verification of the output signal, a current transformer must be connected
between position 6 and position 7 as shown in Figure 5-1. EUT Supply Input must
