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 browser. An important feature of Canvass is the ability to show data from multiple devices on a single stripchart graph. Due to the diversity of devices that can feed data into Canvass, it’s often the case that different nominal voltage levels are in use, and present on a single graph. In this situation, per-unit scaling is essential for comparing voltage traces graphically. This white paper discusses the usage of the per-unit graphing feature of stripcharts in Canvass.
