This instrument is designed to maximize testing capabilities in a lightweight, sturdy format. Additional testing capabilities have been added to the tester, to make it a more comprehensive tool for predictive maintenance. As with the other digital testers, the D3R/D6R/D12R high precision testing capabilities allow data collection in the shop or the field. The results can then be printed immediately or stored for later use. As with many Baker instruments, this machine is IEEE compliant.

  • The D3R/D6R/D12R Digital Winding Tester 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 phased due to turn count differences, along with locating 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 wires insulation, 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 "D" series captures the surge test waveform, remembers it, displays it indefinitely, and prints it to a printer
  • The D Series tester can be used to test all rotating fields of a synchronous motor by storing the waveform from a surge test on one coil. It 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
  • The "D" Series Tester can be operated on its own in the field, and then data can be transferred to a computer running Baker''s Motor Test Acquisition (MTA) software for further analysis. MTA for Windows provides database capabilities, waveform comparison, report generation, printouts,a nd other functions that turns test data into usable information. All options are easily assessed with on-screen prompts
  • Storage of test data for up to 10 motors - 3 Surge Wave Pattern with Amplitude & Time base, Surge Test Peak Voltage Amplitude, DC HiPot Voltage, Leakage Current, Insulation Resistance
  • Baker's QRR reliability High Voltage Design
  • Zero Start Interlock for Tester high Voltage Output
  • Bright, Sharp 5-inch digital display
  • HiPot Over-Current safety warning indicator
  • Input Source Open Ground operator safety disable and warning indicator
