Transmission losses that include corona losses are very common at high voltage power transmission level. The research work investigated the effects of the lengths and the radii of the transmission line sections on the corona loss. Distance values between generating stations and each of the 28 bus stations of the Nigerian 330 kV transmission grid were estimated. As a result, losses were estimated based on the radii of transmission line sections and the distance of load centres to the generating stations. It was discovered that, consideration should be given to these parameters in the design and construction of transmission and distribution lines in order to minimize losses that could result from corona discharge. In addition, losses due to corona discharges are fixed and are independent of the amount of energy being transmitted.
