Distribution Task Team (DisTT)

Contacts

The mission of the NASPI Distribution Task Team (DisTT) is to foster the use and capabilities of synchronized measurement data at the medium-voltage distribution level, beyond the substation.

This group shares information in support of effective research, development and deployment of distribution PMUs and related measurement devices.

We aim to cultivate a community to solve technical and other challenges specific to synchronized measurement technology and its applications in distribution system operation, planning and analysis.
