The concept of a smart electric grid refers to smart computing (information technology) and digital communications capabilities overlaid on the electric distribution network to enable utilities for the first time to have real-time visibility into their end-to-end electric distribution networks. The technology turns every point in the existing network – including every meter and transformer – into a potential information source, able to instantly feed performance data back to the utility. Simply put, it provides utilities with the intelligence required to implement real-time, self-monitoring networks.

AIPA™ BPL technology improves power flow efficiency and reliability, addressing electricity problems before they can grow into brownout and blackout situations that cost the U.S. billions of dollars in lost economic output. The technology also enables enhanced security of the distribution networks, including video surveillance and advanced monitoring capabilities to immediately detect disruptions of power services.

The AIPA™ BPL solution includes three key element which fuel Smart Grid service capabilities.

• Intelligent monitoring devices on every low voltage segment throughout the distribution system. For example, the CT Bridge® collects voltage readings on the low side of the transformer, reports these back to the Current Look™ monitoring system for analysis, and provides an alarm if the voltage is out of the acceptable range.
  
  
• Broadband communications. Since the BPL network overlays a broadband network on the electric distribution system, broadband communications can be used to carry communications necessary for distribution automation, automatic meter reading, and other Smart Grid services.
  
  
• Network Management. The BPL system is monitored and controlled by the CT View® network management system. This ensures that the communications system is reliably available for carrying Smart Grid communications. CT View monitors and aggregates the information collected by the BPL network, such as low voltage measurements. This information can then be reviewed later or the network management system can alert the utility operator to a problem.
