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.
