Applications:
•  Test new and rewound motors before installing to ensure they’re good
•  Test motors during shut-down to detect  developing faults
•  Positively troubleshoot motor & drive trips to identify the problem area; motor, drive, overload, cabling, etc.  
•  When testing installed motors, most tests can be run from the MCC (motor control cabinet) through even hundreds of feet of cable

Test installed motors on-site from the MCC… Or test new, used, repaired & spare motors in the shop or parts room

Your motor drive has just shut the system down!  Is the problem in the motor, the drive, the connections, or the overload?  Maybe you’ve installed a large new motor only to find it won’t run—how could you have detected the fault in advance? 
This off-line tester applies a low voltage AC signal to windings, measures relative impedance & phase angle, and performs a current/frequency response test.  Compare balance of measurements (just like comparing resistance) and you know the condition of the motor.  Also measures insulation resistance up to 500MW with choice of 500V or 1000V test voltages to detect grounded windings & failing insulation.
