Mission

The mission of the NASPI Distribution Task Team (DisTT) is to advance the uses and value of synchronized measurements on or connected to distribution systems of all voltage levels. This group shares information in support of effective research, development and deployment of distribution phasor (PMUs), waveform (WMUs) and related measurement devices/units. We aim to grow a community to solve technical and other challenges specific to synchronized measurement technology and its applications in distribution system operation, planning and analysis.

Point-on-wave data collected on the 20 kV network of EPFL-campus. Visit GitHub to learn more.

Pure and applied metrology

Release Date
Description
A few years ago I joined a team of experts writing a revised standard for phasor measurement units (PMUs), devices that seemed to perform amazing feats of measurement in electric power systems. Not long after I joined the group, I began to be troubled by what we were writing about the measurement of...

Measurement of Phasor-like Signals

Release Date
ERICA Number
PNNL-25643
Description
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...
