ABSTRACT
Electric power transmission
practically deals with the bulk transfer of electrical energy from that carried
at the sending end. Efforts must be made to reduce these losses and increase
transmission efficiency which will increase profitability in electricity
business. Many losses exist in power transmission lines; but this research will
concentrate on only corona losses and ways of reducing or minimizing it since
it is almost impossible to eradicate it. Research has also proven that
increasing the spacing of the three phase in power transmission lines reduce
the effect of corona. However, increasing the spacing increases the line
inductance and hence the reactive power loss along the line which may cause low
voltage (or voltage instability) at load centers. This research will find the
exact spacing between conductors ofthe three phases with which the inductance
caused by the spacing will satisfy recognized standard using graphical method
of analyzed. From the analysis, using 150mm2 size of cable in transmitting
7.5MVA, a conductor spacing of 87cm was found to be the best with corona loss
of 2.80kVA/km and a corresponding reactive power loss of 5.28kVA/km. Further
increase in conductor spacing will although reduce corona loss; the
corresponding reactive power loss will be beyond the acceptable limit.
