Reverse Power Flow in Distribution Feeders
Most distribution feeders were planned around one-way power flow: from centralized generation, through substations and feeders, to customer loads. The rapid growth of Distributed Energy Resources (DERs) — rooftop solar,…
Power Factor Correction and Voltage Regulation
Maintaining acceptable voltage levels along distribution feeders requires careful coordination of voltage regulation equipment and proactive management of reactive power and harmonics. Loads with significant inductive characteristics increase reactive power…
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…
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…
Assessing Impact Loads in PQ Canvass
Impact loads are frequent and very high current surges which are usually greater than the rating of the transformer on which they occur. They present as repeated near-short circuit conditions,…
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…
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…
