Power monitoring
These modules measure active, reactive and apparent power individually for each of the three phases and for
all of them collectively. The power consumption of each phase and the total sum is also recorded. In addition,
the modules provide the RMS values for voltage and current on the three phases. When measuring the current,
the value of the current through the neutral line can also be detected and monitored. Measurement of the mains
frequency and the phase angle of the three phases (current and voltage) complete the power measurement data.
Energy management
The integrated functions on the modules map the immediate power requirements of the machine in detail and also
record its total power consumption. For the user, all relevant data is prepared and made available in the process
image.
The ability to measure currents and voltages up to the 31st harmonic enables higher precision recording of RMS
values. This allows the modules to easily cope with irregular sine curves, and makes them well-suited to renewable
energy applications. In these types of applications, being able to accurately measure the frequency at a resolution
of 0.01 Hz between 45-65 Hz is a great advantage. In general, the modules are suitable for use with 1-phase, 2-
phase or 3-phase power mains.
