SEL-3373

Station Phasor Data Concentrator (PDC)

The SEL-3373 connects to any IEEE C37.118 compliant phasor measurement unit (PMU) or client that adheres to the standard, such as the SEL-3378 Synchrophasor Vector Processor or SEL-5078-2 synchroWAVe Central Software. It is easy to use and configure with the included PDC Assistant Software. Additionally, the SEL-3373 archiving is built in, allowing you to save all PMU data on the solid-state drive (SSD) in the secure database. This ensures that no PMU data are lost if communication with the substation is disrupted. Use the PDC as part of your NERC PRC-002 disturbance monitoring system. Configure up to six different outputs to send data to different locations or organizations, like an independent system operator or a regional coordinating council.

Data Concentration—Concentrate up to 40 IEEE C37.118-2005 phasor measurement units (PMUs) at rates up to 240 messages/second via 2 Ethernet and/or 16 serial ports. Configure up to six independent output streams to provide data to the ISO, neighbor utilities, or your own engineering and operations department, using applications like SEL-5078-2 synchroWAVe Central Software.

Data Archiving—Archive data locally on the optional 60 GB or 120 GB solid-state drive (SSD). You can also configure the SEL-3373 Station PDC to continuously save data to a centralized backup archive. Archives can be continuously recorded or based on PMU trigger bits. Retrieve archived data in COMTRADE or CSV formats.

Reliable Operation in Substation Environments—Reduce your cost of ownership with years of reliable operation, even in harsh substation environments. The Station PDC is designed to operate over a wide temperature range of -20º to +60ºC (-4º to +140ºF) and has no vents or moving parts.

Secure Access—Obtain NERC CIP compliance support with individual user- and role-based account authentication, centralized user authentication using Lightweight Directory Access Protocol (LDAP), strong passwords, user access logs, and port control.

Disturbance Recording—Implement the SEL-3373 as part of your NERC PRC-002-2 Disturbance Monitoring and Reporting solution. Meet the dynamic disturbance recording requirement by archiving PMU data at 30 messages/second.

Substation Data Concentration—Integrate the SEL-3373 Station PDC as part of a wide-area synchrophasor system. Including an archiving PDC in each substation improves system security, reduces the communications bandwidth required to send PMU data, eliminates settings changes at the PMU, and guards against lost PMU data if the communications link with the substation is impacted by an event. Applications like wide-area situational awareness, angle monitoring, system stability assessment, modal analysis, disturbance recording, and more use synchrophasor data provided by SEL-3373 Station PDCs located throughout the power system.


  • Dramatically reduces the time needed to analyze events with wide-area, time-synchronized archives.
  • Plays a key part of an improved situational awareness system.
  • Validates and improves your system models with synchrophasors.
  • Makes it possible to view both real-time and archived phasor data using SEL-5078-2 synchroWAVe Central Software or other visualization applications that use IEEE C37.118 data format.
  • Add additional PMU inputs to concentrate up to 40 PMU inputs.
  • Include local data archiving with storage options of 60 or 120 GB SSD.
