Power systems ideally operate in a balanced state, with equal voltages and currents across all phases. However, real-world scenarios often involve unbalanced conditions that can degrade power quality. Symmetrical components…
Voltage Regulation in PQ Canvass
PQ Canvass is a web-based power quality analysis software developed by Power Monitors Inc. It combines the foundational elements of Canvass with the features of ProVision, providing a set of…
Impact Loading – PQ Canvass
Impact loading occurs from the inrush current of large motors, welding apparatus, electric arc furnaces, or similar loads. The current pulses are less than short circuit values but may be…
Best Practices for Photovoltaic Monitoring Setup
The increasing development and use of solar power generation using Photovoltaic (PV) systems introduces new power quality perspectives and challenges. Understanding common analytic avenues with regard to PV systems can…
Introduction to Voltage Sags
Voltage sags are short-duration power quality nuisances that can wreak havoc on sensitive electrical equipment. Identifying and classifying sags (as well as identifying their sources) can be a tedious and…
PQ Canvass — Getting Started
Power Monitors’ PQ Canvass is the premiere way to view and analyze power quality data. Born from Canvass, our first generation cloud-based system, PQ Canvass is a power platform to…
IEEE 1250 Overview: An Introduction to Power Quality
Whether you are new to the study of power quality, or an experienced PQ pro looking for a quick reference, IEEE Standard 1250 is the place to start. IEEE 1250…
Viewing Power Consumption in the Cloud
Energy usage metering (in kWh) is now available at-a-glance from the PMI Canvass web application. This new feature will save you time while you diagnose internal and customer-facing issues by…
Wireless Power Quality
The time and cost of deploying PQ instrumentation only to return later in order to retrieve it (without the guarantee that the PQ anomaly has occurred) is often times exorbitant.…
Flicker Investigation Strategy
Flicker is defined as fluctuation or wavering in visible light intensity due to voltage variations. These variations in voltage are caused by fluctuations in the load through the system source…
Understanding PMI Data Record Types – Part 1
The job of any power monitor is to record all interesting data and leave unrecorded the vast majority of boring, unremarkable data. The tricky part for a monitor is deciding…
Understanding IEEE Flicker, IFL, Pst, Plt
This white paper covers and explains three of IEEE's most common Flicker definitions: IFL, Pst and Plt. The GE Flicker Curve and how other measurements standards compare to the GE…
