The SKF Static Motor Analyzer Baker DX12 is part of the SKF Static Motor Analyzer Baker DX family. The SKF Static Motor Analyzer Baker DX unit offers more capabilities to analyze all insulation and motor circuits in AC and DC motors, generators and coils. These instruments offer Insulation Resistance (IR), Polarization Index (PI), Dielectric Absorption (DA), DC HiPot/Step Voltage and Surge tests to evaluate all the insulation in motors and coils. The motor circuit can also be analyzed utilizing Resistance, Impedance, Capacitance, Phase Angle and Dissipation Factor/Quality Factor measurements.
Low voltage testing has been added to the Baker DX. This allows for a more complete testing solution for predictive maintenance or shop quality management. The low voltage tests can supply up to 600 mA and frequencies from 50 to 4 000 Hz.
The Baker DX also offers a modular design that allows you to configure a DX with only the test capabilities needed for your specific application. For example, it can be only a high voltage or a low voltage tester or you can add all the capability to have a unit that has both high voltage and low voltage testing capabilities in one unit. Simply configure the instrument to best fit the application in which it will be used.
Note: Surge voltage accuracy meets/based on Z540 Standard four times measurement uncertainty (calibrated within 2,5%).
Features
- 4 to 40 kV voltage testing capability to test fractional HP motors to 40 megawatt generators
