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
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
