Power Network Configurations

You can set up the Logger to work with several power network configurations:

Single-phase voltage

Single-phase voltage, current, power

3-phase voltage

3-phase voltage, 3-phase current, power

3-phase voltage, 3-phase current, neutral current, power

Note

3-phase logging with no neutral current can be done with appropriate
optional accessories (available separately).

Working with Logged Data

Logged data can be evaluated using the PQ Log software to provide the
following:

Amount, date/time, and duration of quick and slow voltage variations

Half-cycle 10 ms-extreme values for 50 Hz (8.3 ms at 60 Hz) MIN

and MAX for each measuring interval

Depth and duration of voltage dips

Correlation between peak current and voltage dips

95%-flicker values according to EN 50160

Number and duration of interruptions

Compliance of harmonic levels with defined limits

Mean and peak values of phase currents

Value of neutral conductor current

Current total harmonic distortion (THD) of phase and neutral

conductor currents

Profile of active, reactive, and apparent power versus time

Monitoring of power factor (PF), and information about effectiveness

of compensation systems

Graphical representations of logging data and statistics
