Implementation of a RightWon in a small distribution substation connecting IEDs, a meter and sensors located on the transformers within the substation
Transformers serve as a hub for collection and distribution of energy changing the voltage level at different locations of the Grid. They are a key component of the Smart Grid.
These components are loosely defined as an automated, widely distributed energy delivery network, characterized by

Figure 1: Scheme for PLC technology. In a TLACS system from Nyx Hemera Technologies a local controller integrates PLC to communicate with the network controller over the AC line and controls each lamp using a standard DALI interface
Street lighting in its many forms - roadway lighting, tunnel lighting, car park lighting and urban lighting - is a major consumer of grid electricity.
All outdoor lighting is, in fact, estimated to comprise 19% of world-wide electricity usage today. For municipalities and businesses with
