The Baker Instruments D12R is a 12 kV Surge / DC Hipot / Resistance Tester.
The Baker D3R / D6R / D12R Series of Digital Winding Testers can perform Resistance, HiPot and Surge tests as well as digitize and store data for future use.
The Resistance test verifies the existence of dead shorts within the turn-to-turn coils, shows any imbalances between phases due to turn count differences and locates poor wire connections or contacts.
DC HiPot testing detects faults in groundwall / earth insulation, and also provides a complete Polarization Index test. The groundwall / earth insulation system consists of the wire and slot liner insulation, wedges, varnish, and sometimes phase paper.
Surge testing detects faults in both inter-turn winding and phase-to-phase insulation systems. Using advanced analog-to-digital conversion hardware, the DR series captures the surge test waveform, remembers it, displays it indefinitely and prints it to the included printer.
The digital winding tester can also be used on DC armatures and fields. The resulting waveform can then be compared to all other bar-to-bar or span tests to detect a winding fault.
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.
