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…
Working with Live Data in PMI View
PMI View’s live data pages show waveforms, phasors, and tabular values from a connected device, updating as you watch, without interrupting an active recording. During initialization, the live data pages…
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,…
Reverse Power Flow in Distribution Feeders
Most distribution feeders were planned around one-way power flow: from centralized generation, through substations and feeders, to customer loads. The rapid growth of Distributed Energy Resources (DERs) — rooftop solar,…
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 Voltage Phase Angle Jumps
Introduction Modern industrial and utility electrical systems increasingly rely on equipment that responds not only to voltage magnitude, but also waveform timing and phase stability. Equipment trips, transfer events, or…
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…
