Migrating electrical power network SCADA systems to TCP/IP and Ethernet networking

Traditional SCADA systems for electricity utilities rely on data transmission over fixed analogue circuits and modems. This method has been satisfactory over the years but it is becoming obsolete and unsuited to today's requirements. The use of TCP/IP technology can overcome the limitations of analogue communications, allow the network to be more flexible in terms of expansion and reconfiguration, and have higher bandwidth potential whilst retaining the qualities essential for SCADA operations.
