Power Network Configurations; Working With Logged Data - Fluke 1745 User Manual

Power Network Configurations

You can set up the Logger to work with several power network configurations
(listed below). You make these settings using PQ Log software while
connected to the Logger using the interface cable. See the PQ Log Users
Manual for details.
Delta system
Delta 2 element system (2 voltage/current transformer)
Wye (Star) system
Single phase
Split single phase

Working with Logged Data

See the PQ Log manual for full details. 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 EN50160
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
