    Eskom’s proposed strategic research into HVDC transmission.
    (EE Publishers., 2005-07) Naidoo, Pat.; Bologna, F. F.; Muftic, Dzevad.; Ijumba, Nelson Mutatina.; Britten, Anthony C.; Pillay, Logan.
    Eskom has recently started a large research and development programme for the study of long-distance HVDC transmission in Sub-Saharan African conditions. This paper explains why the research is being done, what its strategic context and technical scope are, how it is being managed, and the progress made so far.

    Modelling of broadband powerline communication channels.
    (SAIEE Publications., 2011) Mulangu, Chrispin Tshikomba.; Afullo, Thomas Joachim Odhiambo.; Ijumba, Nelson Mutatina.
    This paper develops a new PLC model and investigates the impact of the load, line length, and diameter of the transmission line on the channel transfer function over the frequency range of 1-20 M Hz. The results show that with 42 degrees of freedom, the proposed model leads to an average RM SE value of approximately 5.2 dB. With the same conditions, the Phillips model leads to an average RMSE value of approximately 1.62 dB.

    Rural electrification using overhead HVDC transmission lines.
    (Energy Research Centre., 2012) Chetty, Leon.; Ijumba, Nelson Mutatina.
    One of mankind’s greatest modern challenges is poverty alleviation. The provision of electricity can greatly assist in this regard. The tapping of small amounts of power from an HVDC transmission line represents a solution to this problem especially in rural areas. This paper analyses the dynamic characteristics of a parallel-cascaded tapping station. The results obtained clearly indicate that the parallel-cascaded tapping station proves to be a viable solution to tapping small amounts of power from an HVDC transmission line.
