In the normal single surge equipment test configuration, the unsurged line is grounded. This is shown by the
dotted lines in the top drawing of Figure 33. However, doing this at device test places one terminal pair in
parallel with another terminal pair. To check the individual terminal pairs of the TISP7xxxF3, without any
paralleled operation, the unsurged terminal is left unconnected.
With the generator output open circuit, when SW closes, C1 discharges through R
1
. The decay time constant
will be C
1
R
1
, or 20 x 50 = 1000 μs. For the 50% voltage decay time the time constant needs to be multiplied
by 0.697, giving 0.697 x 1000 = 697 μs which is rounded to 700 μs.
The output rise time is controlled by the time constant of R
2
and C
2
. which is 15 x 200 = 3000 ns or 3 μs.
Virtual voltage rise times are given by straight line extrapolation through the 30% and 90% points of the
voltage waveform to zero and 100%. Mathematically this is equivalent to 3.24 times the time constant, which
gives 3.24 x 3 = 9.73 which is rounded to 10 μs. Thus the open circuit voltage rises in 10 μs and decays in
700 μs, giving the 10/700 generator its name.
When the overvoltage protector switches it effectively shorts the generator output via the series 25
resistor.
Two short circuit conditions need to be considered: single output using R
3
only (top circuit of Figure 33) and
dual output using R
3
and R
4
(bottom circuit of Figure 33).
For the single test, the series combination of R
2
and R
3
(15 + 25 = 40
) is in shunt with R
1
. This lowers the
discharge resistance from 50
to 22.2
, giving a discharge time constant of 444 μs and a 50% current
decay time of 309.7 μs, which is rounded to 310 μs.
For the rise time, R
2
and R
3
are in parallel, reducing the effective source resistance from 15
to 9.38
,
giving a time constant of 1.88 μs. Virtual current rise times are given by straight line extrapolation through the
10% and 90% points of the current waveform to zero and 100%. Mathematically this is equivalent to 2.75
