evaluation.
You can upload and view the harmonics survey data collected
by your device via PAS reports or via common PAS data logs
views.
EN50160 Power Quality Event Log
The EM720 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 PAS (see
Viewing EN50160 Power Quality Event
). Transient overvoltages and short-duration voltage dips
and temporary overvoltages recorded to the file can also be
viewed in PAS 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
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 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
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.
