MIL704D[A][B][C] :STEady state :PHASe :DIFFerence
This test will change phase B program phase angle, if it is selected, from 240 degrees to 236 degrees
for 5 seconds and to 244 degrees for another 5 seconds. The test will be repeated for phase C, if it is
selected.
4.
Steady state waveform distortion (Figure 4).
MIL704D[A][B][C] :STEady state :WAVeform :DISTortion
This test will generate a 5% distortion on the selected phase for 5 seconds.
5.
Steady state frequency test (Figure 5).
MIL704D
:STEady
state
:FREQuency
This test will change the programmed frequency from 400 Hz to 393 Hz for 5 seconds then to 407 Hz
for 5 seconds.
6.
Steady state test
MIL704D[A][B][C]
:STEady
state
This test will perform all the above five tests in the same order above. A 5 second pause between
tests is asserted.
8.6.2. TRANSIENT
1.
Transient high voltage test (Figure 6).
MIL704D[A][B][C] :TRANsient :VOLTage :HIGH
This test requires a 180 volts range. A range change will take place if the power source is not set for
the high range. The output voltage will drop temporarily to allow for range change and after 5 seconds
the test will begin.
The output will go to 180 volts for 10 msec and will drop gradually to 115 volts in 81.25 msec. After 5
seconds, a range change will take place to the original setup. This is a simultaneous test to all
selected phases.
2.
Transient low voltage test (Figure 7).
MIL704D[A][B][C] :TRANsient :VOLTage :LOW
The output voltage will drop to 80 volts for 10 msec. It will gradually rise to 115 volts in 81.25 msec.
This test is a simultaneous test to all selected phases.
3.
Transient voltage test
MIL704D[A][B][C]
:TRANsient
:VOLTage
This test will combine High voltage transient and Low voltage transient. There will be a pause of 5
seconds between tests. If the voltage range is below 180 volts, the High voltage transient test will not
take place.
