voltage level, voltage balance, harmonic
and total distortion, rotor cage condition,
motor efficiency, effective service factor,
overcurrent, operating condition, torque
ripple, load history among others. This
wide range of tests allows exploration of
the true condition of motor integrity and
conditions related to motor performance.
Advanced data collection
and organization
Once testing is completed, results can be
saved and stored for each motor. This type
of documentation is critical for any mainte-
nance program. It allows the recalling of
information for true trending capabilities.
Test results are managed using standard
MS Access relational database file formats.
Reports can be quickly generated through
the main print console, allowing operators
visual confirmation of motor integrity.
The software and data transfer package
enables the creation of multiple databases
to organize collected data to specifications
set by users. This eases communication
channels by handling data in a manner
that is useful, complete and accessible.
Test domains
Power quality
This domain identifies non-optimal power
quality problems, which cause additional
motor stress. Flag frequent problems with
voltage level, voltage unbalance, harmonic
distortion, total distortion, power and
harmonics tests. These issues identify
improper tap settings on supply trans-
formers, poorly distributed single phase
loads, overloading (saturating) supply
transformers, excessive VFDs on low
voltage busses, excessing non-harmonic
frequencies on a VFD, missing line
inductors on VFD applications, missing or
open power factor correction capacitors
along with high resistance connections.
Machine performance
Conclusively evaluate the operation of the
motor, identifying stressful operation and
its source with this domain. It looks at
Effective Service Factor, Load, Operation
Condition, Efficiency, and calculates
Payback Period. Commonly found
problems include: thermal overloading of
the motor, machine deterioration
recognition among other items that are
directly related to the motors health and
the energy wasted with inefficiencies.
Current
Currrent level and current unbalance are
utilized to determine overall electrical
machine health. These parameters are
used to determine the following issues
overloading, connection issues, miss
connections, iron saturation and
improperly wound motors.
Spectrum
This domain has the rotor bar test along
with V/I spectrum, Demodulated
Spectrum, and Harmonics. It shows
current and voltage relationships with
regards to frequency. Electrically it will
find saturation problems, broken rotor
