Operation and parameterization 63
Manual econ sens3 Version 3.0
Current limit
The currents of the 3 phases are checked for currents above the maximum current range. A waveform
for this event is saved. The default value is 3000Arms.
Frequency shift
The network frequency is checked for sudden changes in frequency of more than 1 Hz of the nominal
measurement voltage. A waveform for this event is saved. The default value is 1000mHz.
Vector jump
The measuring voltages of the 3 phases are checked for whether the voltage angle exceeds 30°. A
waveform for this event is saved. The default value is 30°.
Neutral conductor voltage
The neutral conductor voltage is checked for voltages over 10% of the nominal measurement voltage.
The default value is 10%.
Switch on and switch off time
The last switch on and switch off times are documented.
Harmonic current
The measuring voltages of the 3 phases are checked for THDs over 2%. The default value is 100%.
Clock time change
Changes to the internal clock time are documented.
Waveform snapshot
With this function, snapshots (see Measurement submenu in Chapter 8.3) are saved and displayed in
the events list.
Low consumption trigger
With this function, phases of low energy consumption can be defined. In this process, the time
restriction as well as a value limit can be set.
