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 section 4.5.1.1. From any metering display press
PROGRAM, 4, ENTER, EDIT, EDIT, and you should see the following display:
TRANSIENT: PRGM #4
T=0.0002
F=400
Press 1, ENTER, ENTER, to select segment 1 of 1.
TRANSIENT: PRGM #4
T=.0002
F=400
Press 0, ENTER, to select a cycle based transient.
TRANSIENT: PRGM #4
T=1 CYCLE
F=400
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
T=1 CYCLE
F=400
Press 400, ENTER, to select 400 Hz..
TRANSIENT: PRGM #4
