Many electricity suppliers will be installing smart meters during the next few years. It is likely that these smart meters will communicate with the electricity suppliers' control centre using power line carrier(PLC)communications. The CENELEC A frequency band from 9 kHz to 95 kHz is set aside for PLC use by Power Supply Companies. It is also possible for power companies to provide internet access using Broadband over Power Lines (BPL). Such systems can operate at frequencies up to 100 MHz. Several trials of BPL have been carried out in Australia. Recently the Amateur Radio fraternity has been raising a significant concern about high levels of radiation from power lines using PLC or BPL. The two dominant high frequency loss mechanisms in transmission lines are resistive losses and radiation. The radiation models in antenna textbooks do not apply to very long lines like power lines. This paper describes the development, from first principles, of a transmission line model that accurately determines both the resistive losses and radiation losses from any transmission line. This model is then applied to Single Wire Earth Return (SWER) lines, three phase overhead lines using typical conductors mounted on crossarms and aerial bundled conductors. These results show that depending on the cable and signal frequency, BPL and PLC can be achieved without causing any interference. This research is sponsored by ERGON, an Australian Electricity supplier operating in rural Queensland, as part of a project to develop a communication system for SWER lines, so that smart metering, fault detection and enhanced network control can be applied to SWER lines. The results presented in this paper show that for CENELEC-A frequencies, all the losses are small for the power lines considered, making a Smart Grid system using PLC feasible.
