Baker D6000

With a Digital Winding Tester from Baker, you can perform surge and hipot tests, as well as digitize and store test data for future use.

Surge testing detects faults in both inter-turn winding and phase-to-phase insulation systems. Using advanced analog-to-digital conversion hardware, the “D” series captures the surge test waveform, remembers it, displays it indefinitely, and prints it to the included ink jet printer. This surge waveform storage capability can be applied to other motors besides simple induction motors.

The “D”Series can be used to test all the rotating fields of a synchronous motor by storing the waveform from a surge test on one coil, and comparing that waveform to a waveform from every other coil. The Digital Winding Tester can also be used on DC armatures or fields. The resulting waveform can then be compared to all other barto-bar or span tests to detect a winding fault.

DC hipot testing detects faults in groundwall/earth insulation, and also provides insulation resistance and polarization index measurement. Test results from up to 10 motors in the field can be stored, retrieved, printed, and uploaded to a desktop program for file management and analysis. Each of these 10 motor records has its own memory location. Each location can store up to three surge wave patterns plus DC hipot test voltage and current.
