Reference Voltage
As the general approach of the EN50160, all voltage
characteristics are referenced to the nominal voltage that shall
be specified in your meter before running the EN50160
recorders (see
Basic Meter Setup ). The nominal voltage refers
to the line-to-neutral supply voltage in LV networks (4LN3,
3LN3 or 3BLN3 wiring modes), and to line-to-line voltage in
MV networks (4LL3, 3LL3, 3BLN3, 3OP2, 3OP3 and 3DIR2
wiring modes).
Reference Frequency
The nominal line frequency is used as a reference for the
evaluation of power frequency variations. It should be
specified in your meter before running the EN50160 recorders
(see
Basic Meter Setup ).
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 3-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
Device Memory ).
EN50160 PQ Recorder Setup
The PQ recorder setup allows you to adjust the EN50160
evaluation limits (thresholds) for the specific voltage
characteristics in the case the customer requirements differ
from the values provided by the EN50160, and to select the
event and waveform log options for the PQ event log.
