  • An empirical relation for vegetation fuel flames breakdown electric field strength 

    Maabong, Kago Ernest; Mphale, Kgakgamatso; Letsholathebe, Douglas; Chimidza, Samuel; Thebenyane, Phenyo (Scientific Research Publishing Inc., https://www.scirp.org/journal/jemaa/, 2019)
    The compulsion to provide reliable electric power for sustenance of socio-economic development is vital for most of southern Africa states. The demand for the resource in the region is anticipated to escalate in the next ...

  • Measurement of breakdown electric field strength for vegetation and hydrocarbon flames 

    Maabong, Kago Ernest; Mphale, Kgakgamatso; Letsholathebe, Douglas; Chimidza, Samuel (Scientific Research Publishing Inc., https://www.scirp.org/, 2018)
    A significant number of fire-induced power disruptions are observed in several countries every year. The faults are normally phase-to-phase short circuiting or conductor-to-ground discharges at mid-span region of the ...

  • Nondestructive measurement of momentum transfer collision frequency for low temperature combustion plasma 

    Letsholathebe, Douglas; Mphale, Kgakgamatso M.; Chimidza, Samuel (Hindawi Publishing Corporation, https://www.hindawi.com/journals/ijap/, 2014)
    Accurately measured momentum transfer collision frequency and electron density for fire plasma enable correct simulation of electromagnetic wave propagation in the medium. The simulation is essential for designing ...

  • Radio Wave Propagation Experiment in Sugarcane Fire Environments 

    Letsholathebe, Douglas; Mphale, Kgakgamatso M.; Chimidza, Samuel; Heron, Malcolm L. (Scientific Research Publishing Inc., http://www.scirp.org, 2016)
    Large fires have an effect of suppressing Very or Ultra High Frequency (VHF/UHF) radio wave signals strength which consequently impact negatively on the efficiency of radio communications at the frequency ranges. Mobile ...
