Increase in the energy demand for domestic purposes as well as in the manufactur-ing industries has led to a rapid and proportional increase in the electrical energy production today. In meeting this huge electric consumption and demand, proper network and supply of electric power has to be in place from the electric energy generation stations to the final user i.e. the consumers at home, in offices and heavy manufacturing industries.
Achieving this goal without mincing safety and security, pose a great challenge to the energy producers. From the proper planning of electrical networks to the me-ticulous and adequate monitoring and control of various electrical substations and power outlets this is in no way an easy task. Transmission of intelligent infor-mation other than kilovolts via normal high and low tension cables posed a great difficulty. Hence, the need to use another means of data communication, precisely wireless communication.
The first solution as used by ABB was a radio frequency modem which turned out not to be able to properly handle the complexity of some electrical networks. Then, GSM modems were introduced but did not last for too long because they suffer from periodic re-establishment of connection and to solve this problem, GPRS modems were introduced in 2003. And now am introducing 3G modems to ABB with its numerous benefits and a major focus on the influence of the round trip delay time and packet loss. To research the significance of this two factors, an emulation program was designed to send and receive data over a 3G modem, data samples were taken and analyzed and it was discovered that the factors considered are significantly minimal when compared to the rest of the previous technologies especially the radio frequency modem. And it can be safely concluded that the 3G modem can be used to replace any of the previous technologies for the purpose of monitoring the electrical power distribution network.
