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,…
