9.6. TEST SPECIFICATION
9.6.1. NORMAL STATE
9.6.1.1.NORMAL STATE MINIMUM VOLTAGE AND FREQUENCY TEST
DO160[A][B][C] :NORMal state :VOLT_FREQ :MINimum
This test will change the output voltage for single phase from 115V to 104V and for
three-phase from 115V to 105.5V and the frequency from 400 Hz to 380 Hz. The test
will last for 30 minutes. The CLR Key in local operation will terminate the test at any
time. Group execute trigger will terminate the test remotely. The unselected phases will
remain at 115 volts.
9.6.1.2.NORMAL STATE MAXIMUM VOLTAGE AND FREQUENCY TEST
DO160[A][B][C] :NORMal state :VOLT_FREQ :MAXimum
This test will change the output voltage for single phase from 115V to 122 volts and from
115V to 120.5 volts for three-phase and the frequency from 400 Hz to 420 Hz. The test
will last for 30 minutes. The CLR Key in local operation will terminate the test at any
time. Group execute trigger will terminate the test remotely. The unselected phase will
remain at 115 volts.
9.6.1.3.NORMAL STATE VOLTAGE UNBALANCE
DO160[A][B][C] :NORMal state :VOLTage :UNBalance
This test will change the output voltage for each phase from 115 volts to 112 volts and to
118 volts. The test for all three phases will last 30 minutes. The test can be terminated at
any time.
9.6.1.4.NORMAL STATE WAVEFORM DISTORTION
D0160[A][B][C] :NORMal state :WAVe form :DISTortion
This test will generate a 5% distortion on the selected phase. The test will last for 30
minutes. This test can be terminated at any time.
