Chapter 8 Configuring Recorders Configuring the EN50160 Power Quality Recorder
SA300 Substation Automation Unit 103
Compliance with the EN50160 requires that the 3-second mean of signal voltages
shall be less or equal to the specified limits for 99% of a day.
Configuring the EN50160 Recorders
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 the SA300 by the secondary line-to-line
voltage (see
Basic Device Setup ) regardless of the wiring mode. 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 device before running the
EN50160 recorders (see
Basic Device Setup ).
EN50160 Evaluation Limits and Options
Limits for evaluation of the EN50160 voltage characteristics may 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 device 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 device 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.
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 device 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.
