• Calculates RMS values from currents and voltages
• Calculates active, reactive and apparent power
• Phasing detection
• Measures individual phases and calculates cumulative values
• Optional measurement of current through the neutral conductor
• Calculates frequency and harmonics with high precision
• NetTime timestamp: Moment when measured value groups are read
Power monitoring
These modules measure active, reactive and apparent power individually for each of the 3 phases as well as all of them collectively. The power consumption of each phase is also recorded individually and in total. In addition, the modules provide the RMS values for voltage and current on the 3 phases. When measuring the current, the value of the current through the neutral conductor can also be detected and monitored. Measurement of the mains frequency and the phase angle of the 3 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 as well as 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 than is generally possible. 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, for example , being able to accurately measure the frequency at a resolution of 0.01 Hz between 45 and 65 Hz is a great advantage. In general, the modules are suitable for use with 1-phase, 2-phase or 3-phase networks.
NetTime timestamp of readout moments
For many applications, not only the measured value is important, but also the exact moment when a group of measured values is read out. The module is equipped with a NetTime timestamp function for this that supplies a timestamp for the recorded position and trigger time with microsecond accuracy.
The timestamp function is based on synchronized timers. If a timestamp event occurs, the module immediately saves the current NetTime. After the respective data is transferred to the CPU, including this precise moment, the CPU can then evaluate the data using its own NetTime (or system time), if necessary.
