Figures 4-9
Figures 4 to 9 follow this page. The individual
figures may not be identified with the Figure
number, but are in order as follows:
Figure 4: Actual measured waveform of the
Voltage rise time. Voltage rise time is defined as
follows (per ANSI/IEEE C62.41 and other
standards): trise = 1.67(t
90
- t
30
), where t
90
and t
30
= the times of the 90% and 30% amplitude
points on the leading edge of the waveform.
Figure 5: Calculated (theoretical) Voltage rise
time based on a computer simulation using the
ideal component values. Voltage rise time is
defined as follows (per ANSI/IEEE C62.41 and
other standards): trise = 1.67(t
90
- t
30
), where t
90
and t
30
= the times of the 90% and 30%
amplitude points on the leading edge of the
waveform.
Figure 6: Actual measured waveform of the
Voltage duration. The duration is defined (per
ANSI/IEEE C62.41 and other standards) as the
time between virtual origin and the time of the
50% pint on the tail. The virtual origin is the
point where a straight line between the 30% and
90% points on the leading edge of the waveform
intersects the V = 0 line.
Figure 7: Calculated (theoretical) Voltage
duration based on a computer simulation using
the ideal component values. The duration is
defined (per ANSI/IEEE C62.41 and other
standards) as the time between virtual origin and
the time of the 50% pint on the tail. The virtual
origin is the point where a straight line between
the 30% and 90% points on the leading edge of
the waveform intersects the V = 0 line.
Figure 8: Calculated (theoretical) Current rise
time based on a computer simulation using the
ideal component values. Current rise time is
defined as follows (per ANSI/IEEE C62.41 and
other standards): trise = 1.25(t
90
- t
10
), where t
90
and t
10
= the times of the 90% and 10%
amplitude points on the leading edge of the
waveform.
Figure 9: Calculated (theoretical) Current
duration based on a computer simulation using
the ideal component values. The duration is
defined (per ANSI/IEEE C62.41 and other
standards) as the time between virtual origin and
the time of the 50% pint on the tail. The virtual
origin is the point where a straight line between
the 10% and 90% points on the leading edge of
the waveform intersects the I = 0 line.
