MONITOR - METER DATA ANALYSIS
This section is devoted to the meter data analysis and allows to display in the main chart
the trend of the main variables, like Current/Power Factor for each individual phase,
System voltage (star and line), Power (active and reactive system power), analogue
variables like Temperature, signal from pulse and analogue input (when available and
anyway coming from VMU-
P EM modules). Click on the “Monitor” icon in the Navigation
menu to access the screen shown below:
Production data analysis
It is possible to select both the target meter a
nd the variables’ trend; the available trends
are:
