Product Overview: Megger Baker DX Motor Analyzer

Megger Baker DX

In an industrial setting, the consequential cost of failure or unplanned downtime of critical rotating machinery can be significant. The Megger Baker DX series can apply a wide set of off-line electrical tests to assess the condition of motors and coils.

In a motor repair shop, or for new production motors, the Baker DX gives confidence that a motor is correctly wound and insulated, before it’s deployed in the field.

The standards-compliant surge test – a signature feature of Baker testers for decades – is the only test that can safely expose turn-to-turn insulation weaknesses. The Baker DX can find early indications of insulation weakness and faults in windings, between phases, coil-to-coil and in groundwall insulation. It can identify if contamination is impacting insulation strength. It can also detect problems with connections such as feed cable insulation weakness, motor imbalances, opens or high resistance.

The Megger Baker DX’s benefits can be extended to low-impedance coils, such as armatures, through the use of the Baker ZTX low impedance coil accessory. The ZTX, which includes the ATF5000 commutator probe accessory, allows the DX to apply surge tests to coils which require higher currents.

High and low voltage testing capacity in one unit to test the motor circuit and all the insulation.
Intuitive graphical user interface with touch screen.
USB printer interface to quickly print results.
Fully test DC motors.
Modular design to meet your testing needs.
The smallest, lightest surge tester on the market.
Select models come with armature testing capabilities.
Select models come with partial discharge capabilities.

High voltage equipment can suffer from partial electrostatic discharge, where localized corona or breakdown discharge can damage insulation, leading to progressive degradation and eventual circuit breakdown.Winding insulation defects of this type can be found early with the optional Baker DX Surge PD capability, which captures inception, repetitive inception, repetitive extinction and extinction voltages of partial discharge (PD) in accordance with the IEC 61934 standard. PD waveforms and data are included in reports generated by the Baker DX and the Surveyor DX desktop PC software application.

DC motor testing is quick and accurate using the Baker DX. The tester includes an armature test mode user interface and reporting function. Interpole and field coil test results are specially labelled. Bar-to-bar and span tests can be performed on a DC armature to thoroughly analyze for shorts, open circuits, weak turn-to-turn insulation, unbalances in the coils, and damaged or misconnected commutator risers and equalizers. For the best armature diagnostics, the Baker DX can be used with the Baker ZTX low-impedance test accessory, which enables bar-to-bar testing on most DC armatures. The Baker ZTX lowers the maximum surge test voltage and increases the available surge current for testing very low impedance coils.The Baker DX-15A features integrated ZTX technology built into the instrument.
