Astrid Brownout Detector

On this page you will find a record of the most recent drop in mains voltage resulting in a "Brownout" for the ASTRID ring.

  • For a description of the system, see IFA Brownouts Description.
  • See also the Astrid Mains Monitor plots, which shows the RMS voltages for the last 1 h and 48 h.

Notice this service is provided "on best effort only" (no guarantee of availability). The service will occasionally not be operational due to updates.


Last Brownout Time: 29/06-25 - 4:03:29
Last Brownout Values:
    L1: Brownout Value=0.110, Duration=0.040 s, Minimum (one-period) RMS value=205.4 V
    L2: Brownout Value=0.065, Duration=0.020 s, Minimum (one-period) RMS value=202.7 V
    L3: Brownout Value=0.311, Duration=0.040 s, Minimum (one-period) RMS value=179.6 V
The brownout value corresponds to the number of full 50 Hz cycles missing. Values below ~0.5 will generally not be a problem for most equipment.
Last data update: Mon 30 Jun - 14:29


Note that sometimes the browser needs a forced refresh (Shift-F5) to update the graphs.
