2. Electric motors are often deemed to be critical infrastructure, and continuity of production
process depends on this infrastructure. That is why numerous preventive measures are
developed in order to help us avoid unplanned and expensive repairs.

3. Mutual correlation of data captured
with the use of several different
measurement devices (such as
thermal imaging devices, vibrometers
or electrical quantities meters)
requires large amount of work
connected with transferring data to
computer and processing of these
data. There is a possibility to optimize
the abovementioned processes with
the use of state-of-the-art technologies

5. Thermal imaging and load measurment
An important parameter that has to be taken into account while performing infrared
measurements is an electrical load of equipment under test. In case of electrical
apparatus and equipment, electrical load should be at least 40% of nominal rating.

6. Overall vibration measurements
Vibration measurements for rotating machines is one of diagnostic tools that can
indicate deterioration of machine condition from 1 to 9 months prior to the occurrence
of breakdown.
The data registered by the
vibrometer were then
compared against the
overall vibration levels
stated in the ISO 10816-1,
10816-3, and 10816-7
standards, and the results
are presented in Table 2.

7. Thermal imaging and load measurment
The comparison of the value registered
by the vibrometer, thermal camera or
clamp meter against the benchmark
enabled appropriate machine status to
be assigned in the app. Measurements
conducted over a longer period allow
automatic generation of vibration
trends in the cloud.

The mobile app and the technology
for transferring data from
measurement devices to the cloud
enabled providing support for the
preventive maintenance system.
Assigning the appropriate device
status based on the analysis and
correlation of numerous
measurements of electric and non-
electric values allowed accurate
planning of the tasks to be
performed during overhaul
downtimes.
