ARRA SGIG American Transmission Company (Phasor Measurement Unit Project)

American Transmission Company LLC’s (ATC’s) Phasor Measurement Unit project deployed synchrophasor technologies to expand collection of synchrophasor data from 25 to 70 substations across the company’s service area. The project deployed phasor measurement units (PMUs) and data collection software, and digital fault recorders (DFRs) were upgraded to achieve PMU functionality. This project was associated with ATC’s Enhanced Supervisory Control and Data Acquisition and PMU Communications Backbone Project, another project funded through the Smart Grid Investment Grant program.
