In an industrial setting, the consequential cost of failure or unplanned downtime of critical rotating machinery can be significant. The 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.
