4.
Transient high frequency test (Figure 8).
MIL704D
:TRANsient
:FREQuency:HIGH
This test will step up the frequency from 400 Hz to 425 Hz. The frequency will step down to 400 Hz in
the following sequence:
425
Hz
for
1
second
420
Hz
for
4
seconds
410
Hz
for
5
seconds
407
Hz
for
4
seconds
5.
Transient low frequency test (Figure 9).
MIL704D
:TRANsient
:FREQuency:LOW
This test will step down the frequency from 400 Hz to 375 Hz. The frequency will step up to 400 Hz in
the following sequence:
375
Hz
for
1
second
380
Hz
for
4
seconds
390
Hz
for
5
seconds
393
Hz
for
4
seconds
6.
Transient frequency test
MIL704D
:TRANsient
:FREQuency
This test will combine the high frequency transient and the low frequency transient. There is a pause
of 5 seconds between tests.
8.6.3. ABNORMAL
1.
Abnormal overvoltage test (Figure 10).
MIL704D[A][B][C]
:ABNormal
:VOLTage
:OVER
This test requires a 180 volt 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 the range change and after 5
seconds the test will begin.
The output will go to 180 volts for 50 msec and will drop gradually to 125 volts in 450 msec. The
output voltage will remain at 125 volts for 9.5 seconds before it drops to 115 volts. After 5 seconds, a
range change will take place to the original setup. This is a simultaneous test to all selected phases.
2.
Abnormal undervoltage test (Figure 11).
MIL704D[A][B][C]
:ABNormal
:VOLTage
:UNDer
The output voltage will drop to 0 volts for 7 seconds. It step up to 100 volts for 3 seconds before it will
go to 115 volts. This is a simultaneous test for all selected phases.
