Voltage Regulation: Standards-based Compliance
Voltage regulation—the ability to maintain steady‑state RMS voltage within acceptable bounds—affects equipment performance, protection, and customer experience. Distributed energy resources (DER) add complexity via bidirectional power flow and daytime voltage…
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…
Streamlined PQ Analysis with the Latest PMI View Updates
Introduction PMI View for iOS continues to evolve with new features and improvements since our last white paper. This document highlights the significant additions that enhance your ability to perform…
Why Notching Disrupts Power Quality and How To Stop It
Wave notching is a type of voltage distortion that appears as a very fast, repetitive dip or "notch" in the sinusoidal waveform of an AC power system. This periodic disturbance…
Identify Resonance & Distortion With PQ Canvass 3D Graphs
Modern loads convert the utility AC voltage into DC for use internally; this process generates harmonic currents. Harmonic currents can necessitate transformer derating, introduce voltage distortion, and even cause false…
The Right Way to Measure Power in Three-Wire Delta Systems
Introduction Three-phase power systems are the standard for electrical distribution in industrial and commercial applications. Delta systems often have unbalanced loads making it mathematically impossible to accurately measure the power…
Why You Should Transition ProVision to PQ Canvass
Introduction If you own a Power Monitor’s recorder you’re probably quite familiar with ProVision. If you aren’t, it’s Power Monitors’ Windows desktop application that lets you manage your PMI recorders,…
Delta (Line to Line) Voltage
In the world of electrical engineering and power distribution, understanding the relationship between different voltage types is essential. One of the key distinctions in three-phase power systems is the difference…
Smarter PQ Search with AI
This paper introduces an enhancement to PQCanvass: natural language document retrieval powered by vector embedding technology. This feature enables engineers to search Power Monitors Inc.’s white paper library using conceptual…
Line and Phase Voltage in PQ Canvass
PQ Canvass now supports viewing RMS Voltage in a virtual Delta hookup (Line-Line) when the device is hooked up to a Wye configuration (Line-Neutral) and initialized as such. This feature…
PQ Canvass and Cybersecurity
PQ Canvass is PMI's next-generation web-enabled power monitoring and analysis platform. Deploying PQ Canvass as a web application provides a number of benefits: analyzing recordings while the recorder is still…
