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 EN50160 PQ Recorder Setup EN50160 PQ Recorder Setup 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.
To configure the PQ recorder:
Select Memory/Log from the Meter Setup menu, and then click on the EN50160 PQ
Recorder tab.
Adjust thresholds and hysteresis for PQ triggers if required. The harmonic and
interharmonic voltage limits can be individually set for each harmonic order via the
EN50160 Harmonics Setup. Limits for the signaling voltage frequencies are automatically
taken from the “Meister-curve”.
Check the Enabled box for the voltage characteristics you want to be recorded to the PQ
event log. You can individually enable or disable recording PQ events related to specific
characteristics. Notice that the interharmonic voltage and mains signaling voltage
evaluation should be also enabled in the meter via the EN50160 Advanced Setup.
Disabling recording events to the PQ log does not prevent the evaluation of the voltage
characteristics and collecting the EN50160 statistics for these events.
Select the waveform logging options for PQ events.
Download your setup to the device.
The picture above shows the default PQ recorder settings. The available options are listed
in the following table.
