Conducting Surge tests with the Baker PP24 single-phase test lead power
pack
1) After setting up the power pack and analyzer, on the Baker AWA-IV, select the motor
to be tested from the Explore tab.
2) Click on the Tests tab to get to the main testing screen then select a Test ID that uses
a voltage requiring the power pack, or create a test that does.
3) Click on the test configuration button at the end of the Surge Test row. The Surge
Test setup window will appear.
4) Adjust the voltage required so that surge voltage is at least 5000 volts.
5) In the
Surge Test setup window, check the Enable Power Pack box. An error
message will appear on the Baker AWA-IV screen if the power pack option is selected
and accepted and no power pack connection is detected.
6) Click on the Pause between Leads button in the Surge Test setup window.
7) Turn the Voltage Output Control knob on the power pack to Min (full
counterclockwise).
8) Select the Surge test using the Function knob on the power pack.
9) Connect the power pack leads to the motor as shown in the following table.
Table 7. Single-phase leads; Surge test connections.
Red (Energized) Black 1 (Grd) Black 2 (Grd) Black 3 (Grd) Black Braided (Grd)
Motor phase A Motor phase B Motor phase C Motor frame
Motor frame or
station ground
Motor phase B Motor phase A Motor phase C Motor frame
Motor phase C Motor phase B Motor phase A Motor frame
10) Connect the safety ground (the smaller diameter black ground lead) to the frame of
the test winding and not to the coil ground lead. Results of the surge test will be
erroneous if the coil ground is used instead of the frame grounding.
11) To start the Surge test, click on the Lead 1 button in the Run Surge section of the
Surge Test setup window. If you attempt to start by using the power pack’s push to
test button, you will see a message instructing you to use the Lead 1 button.
12) After selecting the lead to test, start testing by pressing the power pack’s Test button
(or footswitch) and slowly raise the test voltage using the power pack’s Voltage
Output Control knob. Test results should immediately be visible on the analyzer’s
screen. If not, recheck the connections and switch settings. Also, ensure that the
interconnect cables have been attached and are secure.
13) Continue to hold the Test button (or footswitch) for the duration of the test.
14) When the test has completed, release the Test button (or footswitch) on the power
pack and return the Voltage Output Control knob to its minimum setting.
15) Switch the leads according to the table above to surge different motor leads. Repeat
steps 11–15 until all phases have been tested.
16) When you have completed testing all leads, click on the Close button.
17) If test results should be saved, click the Save Results button on the Main window,
Tests tab.
