Revolution Download in PQ Canvass
Revolution meters are compact, cellular-connected power monitors. Unlike the Tensor, Seeker, Guardian, and Bolt devices, which initiate their own uploads to PQ Canvass, Revolutions do not push their recordings to…
Wireless PQ Monitoring with the Javelin and Revolution
Introduction The Javelin is a utility-friendly cell router, providing communication access to devices in the field such as capacitor controllers, reclosers, voltage regulators, and DER inverters. A Javelin may also…
Ferroresonance in Solar Step-Up Transformers
This paper explores the unique risks of ferroresonance within solar photovoltaic (PV) installations, specifically focusing on the interaction between step-up transformers and system capacitance. We will examine why solar sites…
Voltage Unbalance Within PQ Canvass Compliance Reports
Power Monitors, Inc.'s PQ Canvass is a secure, cloud-based platform built for power-quality (PQ) analysis. PQ Canvass has a beta feature of automated "compliance reports" that transform data uploaded from…
Symmetrical Components from Stripchart Data
Symmetrical components can be useful in a PQ investigation, especially in cases of voltage imbalance, where the customer's negative sequence current can help determine their contribution to the imbalance. Many…
Using PQ Canvass
