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…
PMI View Feature Updates and Enhancements
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…
Auto-Correction of CT Hookup
Sometimes when hooking up CTs for a device, a user will inadvertently place the CTs in the wrong configuration. Maybe the channel 2 CT was placed on the third phase…
Symmetrical Components
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…
