ABSTRACT A channel model suitable for multi-wire overhead medium-voltage lines is proposed. This model is then employed in order to evaluate the multipath channel impulse response and the associated transmission capacity limit in actual overhead medium-voltage power distribution networks for broadband power-line communications applications. Electromagnetic interference limitations of such systems are discussed.

    ABSTRACT: For years, some African universities followed the British education system, but this is gradually changing. For example in Ghana, the three terms to the year approach has been changed to the two semester approach. Also, local conditions and the service learning approach are being included in the curricula. This is being done in the Telecommunications Engineering program at Kwame Nkrumah University of Science and Technology. The program is planned such that some student projects for which the students will earn credits will result in products that will supply community needs. The program is therefore community-centered and provides community service. One project using this approach is based on Broadband Powerline Communication (BPL). BPL can be used in electronic learning at schools and to disseminate information to the community at large. It will empower the people and lead to improving their standard of living. It can also help the nation to become a full participant in the global community, while benefitting from the global economy. This paper describes how this project was designed to suit service learning through an experiential teaching method.

    ABSTRACT: In this paper, human exposure to a simple outdoor PLC system is assessed. An electric field irradiated by the PLC configuration is calculated using the wire antenna model. For the frequency range from 1 to 10 MHz the human body is represented by the equivalent thick cylindrical antenna, while in the range from 10–30 MHz a parallelepiped body model is used. The axial current density distribution induced along the body as well as the values of surface and whole body averaged SAR, are calculated and compared with limits defined by relevant international standards.

    ABSTRACT: Using the Medium Voltage(MV) distribution line as a communication medium of the distribution automation and public communication could also be a cost-effective, advantageous and effective way compared to other systems because it is an existing infrastructure. In order to investigate MV PLC's signal leakage interference & transmission characteristics at frequency range from 20 to 500 kHz, the attenuation, impedance, noise and interference at different Voltage power line were measured, and the results of statistical analysis have been achieved by PC. Furthermore the effects of MV PLC are discussed. According to DL/T790 series standards (IEC61334), the measurement for MV PLC's signal leakage interference is performed, and its results indicate that the spectrum leak of the MV PLC equipment doesn't disturb the work of existed carrier communication system, especially carrier transceiver for relay protection.
