Scientists Identify Cause of Global Grid Pulsing
2 min read
Researchers led by physicist Dirk Witthaut determined that uninterruptible power supplies perform routine battery checks every 60 seconds, causing synchronized surges. Analysis of measurements from four buildings in Germany confirmed the pattern links to digital clock synchronization across independent systems, explaining the 60-second oscillation observed on power grids on five continents.
