Induction motors are ever popular in today’s world and can be found in most areas of life — industrial, agricultural, and even residential settings. These motors can have high inrush…
Voltage Unbalance Within PQ Canvass Compliance Reports
Power Monitors, Inc.'s PQ Canvass is a secure, cloud-based platform built for power-quality (PQ) analysis. PQ Canvass has a beta feature of automated "compliance reports" that transform data uploaded from…
Symmetrical Components from Stripchart Data
Symmetrical components can be useful in a PQ investigation, especially in cases of voltage imbalance, where the customer's negative sequence current can help determine their contribution to the imbalance. Many…
Getting PQ Data from your SCADA System
DNP3 (Distributed Network Protocol) is a communication protocol used primarily in utilities and industrial settings for automation and control systems. It is designed to enable reliable, secure communication between control…
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…
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,…
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…
PQ Canvass API Access
Introduction Electric utilities rely on power quality monitoring to maintain grid reliability, meet regulatory requirements, and respond to disturbances across their distribution networks. As monitoring deployments grow — spanning substations,…
Datacenter Power IV
High-speed protective devices in modern datacenters, such as low-voltage circuit breakers with electronic trip units (ETUs) offering instantaneous or short-time protection, are documented to operate in cases where standard Power…
Modern Flicker Analysis Using PQ Canvass and Merlin™
Voltage flicker is one of the most common power quality complaints reported by utility customers. The term flicker refers to visible changes in lighting intensity caused by rapid fluctuations in…
