    5.10 Fault current detection Each fault current module provides two channels for monitoring differential or fault currents in earthed AC current systems. In any case, measurement has to be performed via suitable current transformers, a direct measurement is not possible. The module is not suited for monitoring operating currents of normally live conductors (L1, L2, L3, N).

  • Page 50: Pq Monitoring

    7.6 PQ monitoring Power quality monitoring provides both a statistical evaluation, allowing an assessment of compliance with standards (e.g. EN 50160) or supply contracts, as well as records of events in the grid (e.g. power voltage dips). This facilitates the analysis of causes and effects. Conformity reports may also be created directly via the website of the device.

  • Page 51: Pq Statistic

    7.6.2 PQ statistic Power quality (PQ) is assessed by a comparison between the PQ parameters measured by the device and the limits of a contract agreed upon. The assessment period is usually at least one week to take into account possible variations between weekdays and weekends. Via its website the device can perform an assessment of the measured PQ parameters in accordance with the following standards: EN 50160...

For each monitoring function you may select if it is used for building the summary alarm state. If at least one of the used functions is in the alarm state, the summary alarm is also in the alarm state. If an optional failure-current monitoring is present, the detection of an alarm state or a breakage of the measurement line (2mA inputs only) activates directly the summary alarm.
