Motor Testing

Motor Testing and condition Monitoring

Motor circuit analysis (MCA) is a superior test programme to simple megger testing which only provides a momentary glimpse at the condition of a motor’s insulation, but provides no information about other developing conditions within the motor. MCA test results, if understood correctly, not only give DC resistance, impedance, inductance, phase angle, I/F and insulation resistance results, but can also provide information of developing mechanical issues within the motor, such as rotor and shaft faults.

Electric Motor Solutions Pty Ltd Specialist Testing Services has been conducting on-site MCA testing for approximately seven years now. In that time we have successfully advised clients on the condition of their motors up to and beyond 400kW.

One of the most beneficial and satisfying aspects of on-site MCA testing is the ability to determine if the problem in an installation or motor related, or may be control or cable or site supply related. Cost savings achieved by not removing a motor unnecessarily for maintenance, only to find the problem is still present after motor refurbish
and re-installation, can be substantial. Another beneficial aspect of on-site MCA testing is being able to clear a motor of winding damage in the event of supply or control equipment failure, and thus avoid unnecessary removal. On-site MCA testing is also of benefit in understanding motor condition prior to moving transportable equipment
to sites remote from base.

Any on-site MCA test conducted by Electric Motor Solutions Pty Ltd Specialist Testing Services includes the on-site test and provision of a written report showing
computer analysis of the test results achieved.

Electric Motor Solutions Pty Ltd Specialist Testing Services has recently advanced it’s testing capabilities by the addition of highly specialised Baker off-line (static) and on-line (dynamic) computer-based test equipment. Very few of these units exist in Australia, and Electric Motor Solutions Pty Ltd Specialist Testing Services at this time owns the only Queensland-based units. This equipment is portable and can be readily transported to distant locations.

Electric Motor Solutions Pty Ltd Specialist Testing Services has two Level 1 Certified Technicians capable with providing you with thermographic testing and reporting. Only Level I or above certified technicians can legally provide a client with a meaningful interpretation and report.
