Histogram Statistics in Canvass
Histograms in Canvass are powerful, yet underused graphs. In addition to presenting measured data visually, a list of histogram statistics are also computed by Canvass. Histogram graphs in Canvass compute…
Detecting Recloser Events with Boomerang Monitors
Boomerangs provide advanced triggering mechanisms that can be used to detect and send an alert for Recloser events. A "Voltage Low Low" event will be used to trigger an alert,…
Using Standard Deviation To Get More from Daily Profiles
The Canvass power quality portal provides the user many different tools for analyzing voltage, current and power over considerable periods of time. One such tool is the Daily Profile Graph,…
Using Loss of Periodic Load to Trigger Email Alerts
Boomerang triggering mechanisms are most often used for voltage monitoring, detecting overcurrent/high load conditions, or complete loss of load. However, the advanced triggering features in the Boomerang allow for more…
Separating Transmission vs Distribution Events with Canvass
The combination of Canvass and Boomerangs strategically placed in a distribution system allows for a unique system-wide analysis of voltage trends. Analyzing voltage data from multiple locations in parallel reveals…
Threshold Configuration Settings in Canvass
The settings configuration window is a new feature in PMI's Canvass web software. It allows the user to set thresholds for each channel and measure supported by the recorder. When…
Analyzing Apparent and Reactive Power Using Canvass
Canvass, PMI's cloud-based data analysis portal, has recently been upgraded to provide the facilities for apparent and reactive power analysis for plug-in and meter-socket form 2S Boomerangs. This white paper…
Keyboard Shortcuts for PMI Software
Both ProVision and Canvass offer a wide array of user input options. These options range from mouse use to keyboard inputs. Specific keystroke inputs are typically referred to as "shortcut…
Per-Unit Graphing with Canvass
Canvass is a web-based power quality portal designed and developed by PMI to allow users to perform power quality analysis from anywhere they have an internet connection and a web…
Case Study: Impact of Solar Photovoltaic Installations
2012 was a historic year for the U.S. solar industry. There were 3,313 megawatts (MW) of photovoltaic (PV) capacity installed throughout the year, which represents 76% growth over 2011’s record…
Revolution Access via the Canvass Web Interface
