EM720 Power Quality and Revenue Meter
To configure the PQ recorder:
1. Select Memory/Log from the Meter Setup menu, and
then click on the EN50160 PQ Recorder tab.
2. 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".
3. 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.
4. Disabling recording events to the PQ log does not
prevent the evaluation of the voltage characteristics
and collecting the EN50160 statistics for these events.
5. Select the waveform and RMS profile logging options
for PQ events.
6. Download your setup to the device.
The picture above shows the default PQ recorder settings.
The available options are listed in the following table.
