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 EM920 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 PAS reports or via common PAS data logs views.
EN50160 Harmonics Survey Log
Data log file #10 is automatically configured in the EM920 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
Advanced Setup. The evaluation period for harmonics survey
