See EN50160 Evaluation and Recording in Appendix F for
information on EN50160 evaluation techniques.
Basic Device Settings
The following device settings affect the EN50160 evaluation
and should be checked prior to running the EN50160
recorders.
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 or 3LN3 wiring modes), and to line-to-line voltage in
MV networks (4LL3, 3LL3, 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 Log Files
EN50160 Compliance Statistics Log
Data log file #9 is automatically configured in the
PowerSmart Socket PQM for recording EN50160 compliance
statistics. Appendix E lists parameters recorded to the file.
The file is arranged as a multi-section data log file where
each voltage characteristic statistics is stored in a separate
section. Along with EN50160 compliance statistics recorded at
the end of each evaluation period, file also contains data that
may be useful for trouble-shooting power quality problems
for non-compliant voltage characteristics.
You can upload and view the EN50160 compliance statistics
data via Power Software reports or via common Power
Software data logs views.
EN50160 Harmonics Survey Log
Data log file #10 is automatically configured in the
PowerSmart Socket PQM for recording harmonics survey
statistics on a weekly or daily basis. You can see parameters
recorded to the file in Appendix E. The file stores maximum
THD (total, odd and even harmonics) and maximum
harmonic voltages up to order 50 collected within each
evaluation period.
Harmonics survey is normally intended for trouble-shooting
harmonic problems throughout electrical networks. It can be
separately disabled or enabled in your meter via the EN50160
