As electric utilities, industrial facilities, and renewable generation sites expand into remote off-grid locations, reliable cellular connectivity is not always available. Low Earth Orbit (LEO) satellite communications, specifically Starlink, offer…

Seeker+ No-Initialization Recording in PQ Canvass
Every PMI recorder before the Seeker+ starts a recording with an initialization step: the measures, averaging interval, and capture thresholds are chosen up front, bundled into a settings file, and…
Overview of the Seeker+
The Seeker+ runs a power quality survey right out of the box. Mount it, energize it, and it detects the circuit hookup and logs every measure it supports, each aggregated…
Understanding Voltage Swells
If you were to ask a handful of customers what they consider a ‘power surge’ to be, you would get a multitude of answers — anything from a lightning strike…
Introduction to Supraharmonics
As electronic power converters are increasing in prevalence on the grid, especially EV chargers, photovoltaic inverters, variable frequency drives, and LED lighting systems, a new power quality issue is arising…
Event Timing in Power Quality Investigations
In the complex landscape of electrical distribution, identifying the origin of power quality disturbances requires more than just high-speed sampling; it demands precise temporal synchronization across the entire monitoring network.…
Revolution Download in PQ Canvass
Revolution meters are compact, cellular-connected power monitors. Unlike the Tensor, Seeker, Guardian, and Bolt devices, which initiate their own uploads to PQ Canvass, Revolutions do not push their recordings to…
Heat Pumps and the Winter Peak
As American homes shift from gas furnaces to heat pumps, the load that used to burn gas now arrives at the residential transformer — in winter, at the coldest hours,…
Region of Interest (ROI) Snapshots in Merlin™
Power Quality recordings are the primary source of evidence in any PQ investigation. The problem is that these recordings can be weeks long and contain hundreds of captures, which makes…
Merlin™ Document Writer
The Merlin™ Document Writer turns a completed power quality analysis into finished, shareable documents: customer letters, executive summaries, technical reports, regulatory responses, and more. It works from reusable templates that…
Understanding Load Diversity and Its Effect on Power Quality
Introduction Your home and the office building down the street both run on electricity from the same utility, but they don’t typically use it in the same way at the…
Understanding Voltage Phase Rotation in Three-Phase Systems
Three-phase power systems depend not only on equal voltages between phases but also on the order in which those phases reach their peaks — a property called phase rotation. Incorrect…
