Motor Circuit Analysis

Motor Circuit Analysis (MCA) is a deenergized low voltage test method to assess the health of the motor and associated cabling. This method can be initiated from the Motor Control Center (MCC) or directly at the motor. The advantage to testing from the MCC is that the entire electrical portion of the motor system, including the connections and cables between the test point and the motor, will be evaluated. 

MCA™ is a field proven motor testing method that quickly and accurately identifies faults previously difficult or impossible to detect using the older cumbersome (go – no go) techniques. The condition of the ground wall insulation system fails to identify the condition of the winding insulation system or any of the various rotor faults. MCA™ assess the health of the motor while the motor is deenergized. MCA can be used to determine the condition of the ground wall insulation, winding insulation as well as identify squirrel cage rotor faults in induction motors as well as cabling to the control. 

Benefits of MCA™ – Motor Circuit Analysis technology is used for incoming and outgoing inspection of new, repaired motors (motor tags), condition monitoring, preventative maintenance, predictive maintenance (trending asset life) in a safe and quick manner and troubleshooting. MCA quickly detects cable degradation, pitted/eroded contacts, loose connections, developing winding faults, ground faults, winding contamination, and rotor faults. Another benefit of MCA™ is TVS™ (Test Value Static) that tracks the motor asset from the cradle to the grave. TVS™ monitors changes in the motor baseline that alert you to potential motor failure and associated developing problems.

Use of MCA™ technology will help you identify the source of the problem.
