Generic test IDs versus specific test IDs
The Test ID just created is specific to the Delco 460 V motor used in this example. This Test ID
should not be used for another 460 V motor such as a 100 hp/460 V motor. The reason is
that a Target Resistance value of 3.1 ohms—which is specific to this 3 hp Delco motor—was
entered. If this Test ID were used to test a 100 hp motor, the resistance test would fail
because the 100 hp motor will have a much lower winding resistance than 3.1 ohms.
Therefore, if a Test ID is to be used for many motors, the Target Corrected Resistance option
should not be used. Without a Target Corrected Resistance, there is no specific or unique
information that ties the Test ID to a specific motor.
Several generic Test IDs based on machine voltage are included the database. Target
Corrected Resistance checking is disabled for all of them.
Running an automatic test
After a new Motor ID has been created, and a new Test ID for the motor has been created, a
fully automatic test can be run. An automatic test will test the motor in the following
sequence:
1) Temperature
2) Resistance
3) Meg-Ohm
4) PI/DA
5) Hipot/step voltage
6) Surge
At the end of the sequence, the test data will automatically be saved to the database.
For completeness, it must be mentioned that tests can also be run from the test windows
themselves—a process called semiautomatic testing. Additionally, tests can be run manually
using the controls on the front panel of the tester. A semi-automatic test can be run by
pressing the desired test’s button on the tests view.
1) To start an automatic test, make sure the motor is selected within the
Explore tab.
2) Click on the Tests tab to get to the main testing window. If the Motor ID setup and
the Test ID setup procedures were followed as described, the Baker AWAIV should be
at the correct place to begin the automatic test.
3) To start the test, click on the red Run Auto Test button in the Tests tab and follow
the directions.
4) The Safe to Turn On dialog box appears, instructing you to verify that the correct set
of leads is properly connected. If the resistance test is turned on and the Res Leads
box is not checked, this dialog box will direct you to attached the high-voltage leads.
If the Res Leads box is checked, the displayed dialog will request that low-voltage
leads be attached.
