can be selected independently from the EN50160 compliance
evaluation.
You can upload and view the harmonics survey data collected
by your device via Power Software reports or via common
Power Software data logs views.
EN50160 Power Quality Event Log
The PowerSmart Socket PQM provides the EN50160 Power
Quality (PQ) recorder that can detect EN50160 incidents and
record each individual power quality event to the log file with
the start and end timestamps and a fault magnitude. It may
be useful for trouble-shooting problems throughout the
electrical network, for example, to identify and locate the
source of a power quality event and to select an appropriate
solution.
The EN50160 power quality report can be uploaded and
viewed via Power Software (see
Viewing EN50160 Power
Quality Event Log ). Transient overvoltages and short-duration
voltage dips and temporary overvoltages recorded to the file
can also be viewed in Power Software as magnitude/duration
pairs on the well-known ITIC curve chart for assessing the
minimum equipment immunity.
The PQ recorder is programmable to trigger the waveform
recorder to record the fault waveforms before, during and
after the PQ event for detailed event analysis.
EN50160 Evaluation Limits and Options
Limits for evaluation of the EN50160 voltage characteristics
can be set via the
EN50160 PQ Recorder Setup and, for
harmonic and interharmonic voltages, via the EN50160
Harmonics Setup (see
EN50160 Harmonics Limits Setup ).
The EN50160 evaluation options can be changed via the
EN50160 Advanced Setup .
EN50160 Logging Options
The memory allocated in your meter for the EN50160
compliance statistics and harmonics survey data is sufficient
for 13-month data recording on a weekly basis. The Power
Quality event log file is configured for 1000 event records.
You can increase or change the size of the EN50160 data log
files in your meter via the Log Memory Setup (see
Configuring the Data Recorder ).
EN50160 PQ Recorder Setup
The PQ recorder setup allows you to adjust the EN50160
evaluation limits for specific voltage characteristics in the
event the customer requirements differ from the values
provided by the EN50160, and to select options for event,
waveform and RMS profile recording.
