A standard power meter reports RMS averages every second or three. A voltage sag lasts a few cycles. A switching transient lasts microseconds. The meter reports that nothing happened, and the breaker on the floor disagrees. This is why so many electrical problems present as mysteries: the instrument that should explain the trip cannot see…

On July 22, 2026, data centers in Northern Virginia disconnected about 3,800 megawatts of load during a fault the transmission system cleared normally. The generators stayed up. The wires stayed up. The loads left. PJM’s analysis points at load-side sensitivity: protection settings inside the facilities read a survivable sag as a threat and transferred off…

Read time: 2 minutes We Asked AI to Solve Its Own Power Crisis. Here’s What Happened. We conducted an unusual experiment: we asked artificial intelligence to diagnose the very problem that could destroy it. We fed Google’s most advanced AI system over 10,000 pages of electrical engineering knowledge—everything from fundamental textbooks to cutting-edge energy research.…

We appreciate everybody’s interest in why Power Quality is important. There is a more current description of why power quality is important in relation to electrical losses and carbon footprint on our blog here. Thank you for your interest. Almost everyone in the United States uses electricity. Surprisingly, few of them know that there is…
