Conducting DC tests with the Baker PP30 three-phase test lead power pack
1) After setting up the analyzer and power pack, on the Baker AWA-IV, select the motor
to be tested from the Explore tab (motor tree view).
2) Click on the Tests tab to get to the main testing window.
3) Select a Test ID that uses voltage requiring the power pack, or create one that does.
4) Click on the configuration button to the right of the name of the DC test desired. The
DC Tests configuration window will appear.
5) Adjust the voltage required so that HiPot voltage is at least 2000 volts.
6) Enable the power pack by checking the
Enable Power Pack box under the HiPot test
parameter column. An error message will appear if a voltage below the minimum for
the power pack is programmed after the Enable Power Pack box is checked.
NOTE
An error message will appear on the Baker AWA-IV screen if the power pack option
is selected and a power pack is not connected.
7) Turn the
Voltage Output Control
knob on the power pack to
MIN
(full
counterclockwise).
8) Select one of the HiPot settings on the power pack
Function
knob. When the HiPot
100 m Amp/Division setting is chosen, a loud relay noise will be heard.
9) Connect the power pack leads to the motor as shown in the table below.

10) Ensure that the correct test is displayed on the Baker AWA-IV screen.
11) Start testing by pressing the power pack’s test button (or footswitch) and slowly raise
the voltage using the power pack’s Voltage Output Control knob. Test results should
immediately be visible on the Baker AWA-IV screen. If not, recheck the test lead
connections and all the switch settings. Also, ensure that the interconnect cables
have been attached and are secure.
12) Continue to hold the test button (or footswitch) for the duration of the test. Have
HiPot setting at 100 m A/Div to start. Change the micro-amps per division switch as
needed to increase the sensitivity of the data acquisition during test.
13) For example, if target voltage is needed, and at 100 m A/Div you see less then 50 m A of
leakage current, it is best to switch the power pack to 10 m A per division for better
accuracy. If less than 5 m A is leaking at 10 m A per division, switch to 1 m A per division
for best accuracy. (This can be switched during the test).
