11.5 Voltage dip, voltage swell, voltage interruption
Half-period rms values are measured to record these characteristics.
The rms value of the voltage is calculated over an entire period and updated after every half period.
This method combines the accuracy of a full-cycle measurement and the speed of a half-cycle measurement.
11.6 Voltage dip
As soon as the voltage drops below a defined threshold, this is evaluated as a voltage dip.
Limits
In addition to the threshold, a hysteresis can also be configured individually.
Voltage dips are categorized according to table 2 of EN 50160 and the number of dips permitted before it is categorized as a
violation can be defined for each individual category.
In addition, there is a field for categories that are not defined in the table.
11.7 Voltage swell
If the voltage exceeds a defined threshold, a voltage swell is detected.
Limits
In addition to the threshold, a hysteresis can also be configured individually.
Voltage swells are categorized according to table 3 of EN 50160 and the number of swells permitted before it is categorized as a
violation can be defined for each individual category.
There is also a field for categories not covered by the table.
