Datacenter Power Consumption II
The explosive growth of datacenter infrastructure in the United States continues to reshape electricity consumption patterns, now constituting a substantial and rapidly growing share of both total load and peak…
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,…
Phasor Decomposition via Symmetrical Components in Three Phase Systems
Introduction When three phase systems are perfectly balanced sinusoidal waveforms, where the B and C phases are exact replicas of the A phase sine wave, but delayed by 120 and…
PQ Trends Electric Vehicle Charging
The rapid deployment of electric vehicle (EV) charging infrastructure is reshaping electric distribution systems in North America. This white paper provides a focused technical overview of EV charging technologies, emphasizing…
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…
Interharmonics and RMS Variation
Interharmonics occur when a signal is present in a power system where the frequency is not an integer multiple of the 60 Hz line frequency. These can be generated from…
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…
