Chapter 4 PAS Application Software EN50160 Evaluation and Recording EN50160 Evaluation and Recording EN50160 Background The EN50160 European standard “Voltage characteristics of electricity supplied by public distribution systems” issued by CENELEC defines the main physical characteristics of electric energy supplied by low and medium voltage public distribution systems under normal operating conditions. The voltage characteristics are evaluated using a statistical approach.
Chapter 4 PAS Application Software interruptions Temporary overvoltages Transient overvoltages EN50160 Evaluation and Recording less than 3 min Less than 1.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording declared by the EN50160 may differ for characteristics for which compliance limits are specified in the standard, usually one week, and for those for which only indicative values are provided, usually one year. The EN50160 compliance reports produced by PAS provide correct weekly and yearly observation statistics regardless of the evaluation periods used for collecting data.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording The PQ recorder is programmable to trigger the waveform recorder to record the fault waveforms before, during and after the PQ event for detailed event analysis. Methods of Evaluation This section describes methods used by the PM175 for evaluating supply voltage characteristics to ensure compliance with the standard.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording A rapid voltage change is not classified if it crosses a voltage tolerance limit (10% Un), as it would be considered a voltage dip or a temporary overvoltage. Target Values The maximum rate of rapid voltage changes in normally once per hour or less. For voltage variations repeating more than once an hour, amplitude is limited by the flicker index.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording it becomes greater than the end threshold on all affected phases including a threshold hysteresis. The basic voltage dip measurement is one-cycle RMS voltage updated each half-cycle. The voltage dip threshold can be changed in the meter via the EN50160 PQ Recorder setup. Statistical Results The PM175 provides the statistical evaluation of voltage dips using the classification established by UNIPEDE.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording and end on another phase. The fault magnitude is recorded separately for each phase involved. The event duration is measured from the instant at which the voltage rises above the start threshold on one of the phases to that at which it becomes lower than the end threshold on all affected phases including a threshold hysteresis. The overvoltage threshold can be changed in the meter via the EN50160 PQ Recorder setup.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording Target Values The range of voltage unbalance given in the EN50160 is: 2% ( 3% in some areas) for 95% of a week The voltage unbalance compliance limit can be changed in the meter via the EN50160 PQ Recorder setup.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording Target Values The EN50160 does not provide target limits for interharmonic voltages. The ranges of interharmonic voltages selected in the PM175 are: Interharmonic THD 2% for 95% of a week Individual interharmonic voltages shall be less than or equal to the values given in the following table for 95% of a week. Interharmonic order 2 3-15 16-25 Relative Voltage 0.2 1.0 0.
Chapter 4 PAS Application Software EN50160 Evaluation and Recording 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, 3LN3 or 3BLN3 wiring modes), and to line-to-line voltage in MV networks (4LL3, 3LL3, 3BLN3, 3OP2, 3OP3 and 3DIR2 wiring modes).
Chapter 4 PAS Application Software EN50160 Evaluation and Recording 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”.
Chapter 4 PAS Application Software Option On End Log No. Range Checked Unchecked 1-2 EN50160 Evaluation and Recording Default Unchecked Description Enables waveform log when the PQ event ends Specifies the waveform log file used for waveform recording on the PQ event The waveform log options allow recording waveforms both at the start and the end of a PQ event.
