1. Instrument Descriptions Baker AWA-IV 2 kV/4 kV Model Front Panel All Baker AWA-IV series analyzers feature an eight-inch touch screen with a graphical user interface. The interface features a logical layout of touch icons that improve ease of use. - Page 7 AWA-IV 12kV analyzers have three red test leads for low-voltage resistance testing (no black lead). High-voltage test leads The Baker AWA-IV uses high-voltage test leads for surge, Baker ZTX, and DC testing. You must keep the leads clean and dry for best measurement performance.

- Page 20 Some issues can be erroneous high resistance imbalance in coil testing due to increased inductance, inability to polarize for DA/PI testing,or frequency shift in one or more waveform values during surge testing. An erratic PP EAR will often result, and the shift could even trip the EAR limits. www.megger.com...

Page 25: Test Sequence
Basic Testing Procedures NOTE Not all Baker AWA-IV testers have low-voltage test leads. If this option is not available, this screen will be slightly different; however, the test operation is the same. TEST SEQUENCE The following sequence of tests will run automatically. If a test fails, the software will stop the testing process, leads will be discharged and grounded, and you will be presented with choices for continuing testing if applicable. - Page 26 The PI test should not be used as the basis for any motor acceptance criteria. It should be used as a trending and diagnosis tool along with other test results, including the PI curve generated. If the Test ID was set up for a DA test, the test duration will be three minutes (180 seconds). www.megger.com...
- Page 27 During testing, the voltage will be slowly increased on lead 1 to the voltage specified in the Test ID. If no pulse-to-pulse EAR failures are detected, leads 2 and 3 will be tested. A shift to the left in the waveform patterns is a common indicator of weak insulation. Baker AWA -IV Static Motor Analyzer www.megger.com...
