Measurement of Phasor-like Signals

Release Date
ERICA Number

This report is a summary of work done principally in 2015 and 2016. The work began, at a low level of funding and activity, a year or so earlier, in an attempt to understand what exactly was being measured by a device known as a phasor measurement unit. This was important because I was a member of the working group of experts who were writing the improved Standard for PMU (phasor measurement unit) performance.
