Unexpected machine shutdowns are not always caused by mechanical failures.
Voltage dips, harmonics, phase imbalance and electrical fluctuations can affect PLC systems, drives, motors and sensitive electronic equipment.
For facilities experiencing repeated production interruptions, the quality of the electrical supply should also be evaluated.
Power quality describes the electrical conditions under which equipment receives and uses power.
Common problems can include:
These conditions may originate from the facility itself or from the electrical supply network.
Short voltage dips can cause PLCs, variable frequency drives and electronic controllers to reset or trip.
Although the electrical disturbance may last only a short time, restarting the production process can take much longer.
Jaka Energy LV Electrical Installation Inspections can support the evaluation of distribution systems and electrical measurements.
Variable frequency drives, UPS systems and other power-electronic equipment can contribute to harmonic distortion.
High harmonic levels may increase electrical losses and heating in transformers, cables and capacitor systems.
They can also contribute to unstable operation of sensitive equipment.
Yes.
Voltage or current imbalance in three-phase systems can cause uneven loading of motor windings and additional heating.
Persistent imbalance may accelerate insulation aging.
For facilities with large motor loads, phase currents should therefore be monitored periodically.
Thermal imaging can help reveal the effects of certain electrical problems.
Examples include:
Thermal findings should be evaluated together with electrical measurements.
SCADA and energy monitoring systems can provide long-term trends for voltage, current, power and alarms.
This is particularly useful for intermittent problems.
If the same voltage disturbance occurs whenever a specific production machine starts, trend data may help identify the relationship.
Jaka Energy SCADA Automation solutions can support centralized monitoring of electrical measurements and alarms.
Adding large motors, variable-speed drives or other power-electronic equipment can change the electrical behavior of a facility.
After major equipment installation, the effect on the existing electrical distribution system should be evaluated.
Jaka Energy Installation Services support transformer, panel, busbar, cable and related electrical infrastructure projects.
Detailed measurements can be useful when:
Longer recording periods may be more useful than a single short measurement when the problem occurs intermittently.
Yes. Voltage dips and other electrical disturbances can cause PLCs, drives and electronic control systems to trip or reset.
High harmonic levels can contribute to additional losses and heating in transformers and other electrical equipment.
No. Depending on the problem, measurements may also be taken at production panels, motor feeders or other distribution points.
Yes, when suitable measurement devices are integrated into the system, electrical values and alarms can be monitored over time.
If your facility experiences repeated machine stops, overheating or electrical equipment failures, power quality may also need to be evaluated. For electrical inspections, power quality measurements and industrial maintenance services, contact Jaka Energy.
