The NSTAR Electric Company (NSTAR) Grid Self-Healing and Efficiency Expansion project involved deployment of two-way communications infrastructure and distribution automation (DA) equipment on 400 circuits. New switches, sectionalizers, reclosers, and condition monitors were installed to enable automatic detection and isolation of power outages, followed by rapid restoration of functional portions of the circuits.
