Study on corona power loss and audible noise under different electrode configurations / Baharudin Jili

Corona power loss, radio interference and audible noise has been studied extensively all over the world but most of the studies are confined to EHV transmission systems. Very scantly information is available in the literature about power loss and audible noise due to local corona in machines and apparatus. In this thesis, results of an experimental study on power loss and audible noise due to corona under different electrode configurations have been reported. Both, high voltage AC and DC has been used for the studies. Standard electrode configurations such as sphere-plane, rod-plane, rod-rod etc. has been used, keeping in view that the insulation characteristics of most of the machines and apparatus may be approximated to the characteristic of these configurations.
