An elementary module for energy management and power quality monitoring systems In the fi eld of energy management it is very important to be able to evaluate and process data measured for both energy usage and power quality. It should be possible to document all important data measured without interruption, in order to determine reasons for production problems, failures or quality defi ciencies. For example, time stamped data for harmonics, voltage fl uctuations or blackouts facilitate the identifi cation of root causes of possible production problems.
With timely identifi cation of poor power quality it is possible to take steps to avoid the increased wear or destruction of electrical distribution controls and operating equipment and even reduce the risk of fi re. Through the analysis of load profi les and electrical loads it is possible to implement measures to improve energy effi ciency. Within the framework of energy management, targets can be defi ned for energy consumption, CO2 emissions and energy costs. The new standard ISO 50001 has formulated a suitable framework of conditions for an operational energy management system.
