This paper presents a novel technique for the computation of radiated electromagnetic interference levels due to corona on HV transmission lines. The EMI levels due to corona computed for different lines from around the world matches well with the experimentally measured values, thus validating the present technique. Using the technique developed, it has been shown that the radiated field a an observation point close to the transmission line increases with the line length and reaches almost a constant value for line lengths above 1500 m. The influence of increased spacing between phase conductors is to reduce the radiated field where as the type of phase configuration does not have any influence on the radiated field.
