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: 16/07-24 - 19:17:47
Last Brownout Values:
L1: Brownout Value=0.398, Duration=0.080 s,
Minimum (one-period) RMS value=184.9 V
L2: Brownout Value=2.579, Duration=0.080 s,
Minimum (one-period) RMS value=62.4 V
L3: Brownout Value=0.455, Duration=0.060 s,
Minimum (one-period) RMS value=183.8 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.
