Motor Current Signature Analysis (MCSA) are diagnostic technique that are being used to analyze motors, transformers, generators, alternators, distribution and other electric equipment.
This technology has the ability to test on line and off line electrical equipment and identify a variety of mechanical and electrical problems. These techniques can be used to analyze the driver, the driven load and the power supply. As a preventative maintenance tool, Motor Current Signature Analysis Services can be used to perform a one-time test or periodic testing to track and trend motor performance. MCSA allows for remote, non-intrusive testing of the equipment being monitored. The test analyzes the current waveform using complex mathematics. They are non-intrusive, invisible to the equipment being monitored and can be performed from remote connections such as Motor Control Centers (MCC).
The information is captured and thereafter analyzed for the following possible defects:
Rotor bar faults
Stator winding health
Winding lamination defects
Incoming winding health
System load and efficiency
Air gap static and dynamic eccentricity
Coupling health, including direct, belted and geared systems
Our team is able to offer several integrated methods to assess and track the condition of critical plant induction motors.
Testing can be performed online without production interruption
Provide "on the spot" recommendations with no historical information needed
Testing can be done on a primary circuit or safely done on low voltage secondary switch gear
Combining MCSA with standard monitoring techniques such as vibration and temperature (multi-parameter monitoring) to increase decision making confidence
Detect problems such as high resistance joints, cracked end rings, broken or cracked rotor bars and casting porosity or blow holes in die-cast rotors
