Power quality monitoring

Measuring and monitoring power quality parameters provide faster and more accurate information for decision making

Facility and building monitoring systems monitor and analyze the energy consumed, mostly using main multifunction meters (MFM) and by deploying sub-meters at the load.

While this information is helpful in discovering a problem, it is not enough to solve it. The reliable and safe operation of equipment depends directly on the quality of power feeding it.

Fluctuation in energy consumption, failures of systems, irrational behavior of critical assets, etc., could be just a symptom.

For instance, if the current drawn by the HVAC system is significantly higher than normal, the operator knows that something is not working correctly. To find the real cause of the problem, he needs power quality monitoring.

Key values

Reduce Maintenance cost

Maximize sustainability

Reduce electricity bills

Increase equipment lifetime

Enables quick problem identification and solution to reduce maintenance costs and improve reliability. Monitoring voltage unbalance helps to reduce up to 14 percent of premature failures in AC motors

Support CO₂ savings by monitoring a facility’s electrical parameters and reducing the energy waste resulting from poor power quality. Increasing the efficiency of a continuously operating 150 kW system by 1 percent reduces CO₂ emissions by 3.89 t annually

Avoid penalties by verification of performance and compliance with regulations and standards. Improving power factor from 0.7 to 0.9 for a 5 MVA facility saves up to 167 kEUR in electricity bills per annum

Optimizing the power supply and early detection of problems allows longer equipment lifetime.
Monitoring harmonic distortion helps avoid about 50 percent of a transformer's loss of life time due to thermal stresses produced by harmonic currents

Main applications
