8.6. TEST SPECIFICATION
8.6.1. STEADY STATE
1. Steady state voltage test (Figure 1, page 133).
MIL704D[A][B][C] :STEady state :VOLTage
This test will change the output voltage simultaneously from 115 volts to 108
volts for 5 seconds to 118 volts for 5 seconds. The unselected phases will remain
at 115 volts.
2. Steady state voltage unbalance test (Figure 2, page 133).
MIL704D[A][B][C] :STEady state :VOLTage :UNBalance
This test will change the output for phase A from 115 volts to 112 volts for 5
seconds and to 118 volts for 5 seconds. The test will repeat itself for phase B and
phase C if they are selected.
3. Steady state voltage phase difference test (Figure 3, page 133).
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, page 133).
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, page 133).
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.
