Unlock Faster, Smarter Power Quality Analysis

Power quality investigations often require comparing both Line-to-Line (Delta) and Line-to-Neutral (Wye) voltages—but traditional monitoring setups force users to choose one or physically reconfigure equipment between recordings. With PQ Canvass, that limitation is gone.

A recent update to PQ Canvass introduces Delta voltage viewing—even when a device is installed in a Wye configuration. Supported on Seekers, Bolts, and Guardians (firmware 1.74+), this feature enables seamless switching between Phase and Line voltage views across stripcharts, daily profiles, histograms, and waveforms—no re-initialization or site visit needed. Engineers and utility teams gain instant access to deeper insights into phase relationships, unbalanced loading, and three-phase issues such as single-phased capacitor banks. With both voltage types available from a single recording, compliance checks and customer troubleshooting are significantly faster and more effective.

You'll also find a detailed walkthrough of how to use the Delta view in PQ Canvass and PMI View, complete with screenshots for both Windows and iOS. The guide highlights how phase-angle shifts and magnitude differences—often hidden in Wye views—become clear in Delta graphs. These visualizations help identify subtle PQ problems early and reduce the need for repeat recordings.

Whether you're investigating voltage imbalance, verifying distributed generation behavior, or simply aiming to get more from your existing data, this white paper delivers a practical, time-saving solution.
