4.5.2.2 CYCLE BASED TRANSIENT EXAMPLE
The following is an example of how to create a cycle based transient. This example presumes the user has
loaded the program information as described in the previous examples.
Start with program #4 example as shown in (
). From any metering display press
PROGRAM, 4,
ENTER, EDIT, EDIT,
and you should see the following display:
TRANSIENT: PRGM #4 SEGMENT #1 OF 1
T=0.0002 Va=108 Vb=108 Vc=108
F=400 WFa=1 WFb=1 WFc=1
Press
1, ENTER, ENTER,
to select segment 1 of 1.
TRANSIENT: PRGM #4 SEGMENT #1 OF 1
T=0.0002
Va=108 Vb=108 Vc=108
F=400 WFa=1 WFb=1 WFc=1
Press
0, ENTER,
to select a cycle based transient.
TRANSIENT: PRGM #4 SEGMENT #1 OF 1
T=1 CYCLE Va=108 Vb=108 Vc=108
F=400 WFa=1 WFb=1 WFc=1
Press
122, ENTER, 122, ENTER, 122, ENTER,
to enter 122 volts on all three phases. Note 122 volts is
higher than the 108 volts of the steady-state program. This will cause the base sine wave to remain at a
constant amplitude while adding extra voltage for the spikes.
TRANSIENT: PRGM #4 SEGMENT #1 OF 1
T=1 CYCLE Va=122 Vb=122 Vc=122
F=400
WFa=1 WFb=1 WFc=1
Press
400, ENTER,
to select 400 Hz..
TRANSIENT: PRGM #4 SEGMENT #1 OF 1
T=1 CYCLE Va=122 Vb=122 Vc=122
F=400 WFa=1 WFb=1 WFc=1
Press
15, ENTER, 15, ENTER, 15, ENTER
to select waveform #15 on all three phases.
