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.
