Circuit and CT Hookup Detection with the Seeker+
Setting up a power quality recorder has always meant double-checking the circuit type and every current transformer (CT), the clamp that measures current. A CT on the wrong phase or…
How Distribution Automation Impacts Power Quality Monitoring
Distribution automation replaces operations that used to require a crew in a truck with operations a device performs on its own, in seconds, without anyone watching. A power quality monitor…
PMI Recorders and Starlink
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…
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.…
Detecting Loose Neutrals with Merlin™
A loose neutral is one of the most dangerous faults a single-phase service can develop, and one of the least likely to announce itself. The connection does not fail outright.…
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…
