Fault Distribution for low (left) and medium (right) voltage motors
As opposed to traditional vibration and current signature analysis, this approach uses a
cause-effect (input-output) relationship and therefore is immune to the surrounding noise
or noise in the inputs. Also the difference between expected and actual behavior filters out
and enhances ONLY abnormalities generated by the system, which allows for earlier and
more accurate warnings. The expert system approach eliminates the need for a database or
record keeping, expert personnel, time-consuming data gathering and analysis. It provides
comprehensive (mechanical and electrical as well as driven system) fault coverage though it
measures only voltages and currents.
AMU uses the electric motor of the equipment as a sensor. Therefore, any fault of the
equipment that affects the motor or the three-phase system is also observed by AMU.
4.2. Reporting
Artesis AMT Toolkit was developed to meet a market requirement for a portable condition
assessment product that can provide simple and accurate maintenance scheduling
information, without the need for interpretation by highly trained personnel. It aims to be
very simple to install, set up, and operate, and to require little or no user intervention until
an equipment fault is detected.
Once the AMU unit is switched on, it requires minimal user configuration before entering
an automated ‘learn’ mode during which the complete normal operating condition of the
connected system is established. When this is complete, after 30 minutes, the AES for AMT
software creates a complete Condition Assessment Report for the connected equipment.
Unlike conventional systems, this information is provided to the user immediately without
having to wait for data trends to be collected and analyzed over an extended period. This
