Events
The events setting screen for recording acc. to EN 50160 is shown in Fig. 34.
Use this screen to set:
• Swell, dip and interruption detection thresholds. These thresholds are set as a percent of the
nominal voltage which should be added to the nominal value.
For example: the swell tolerance of +10% Un means that for the voltage Un=230 V, the swell
threshold Uswell = 230 + 23 V = 253V.
The interruption tolerance set at -99% Un means that the detection of the interruption event
takes place at the voltage equal to or greater than Uswell = 230 – 227.7V = 2.3V.
• Recording of the waveforms at the beginning and the end of detected events. It can be set
independently for each of 3 event types.
• Short-term/ long-term interruption threshold. This value is used for the classification of the
interruption events.
