Instability of a swirling annular liquid sheet in swirling inner and outer air streams has been investigated by a temporal linear stability analysis. The effects of the swirling and axial motion of the liquid and the air streams, as well as the effects of relative inner and outer air swirl orientation with respect to the liquid swirl direction on the(More)
—Polymeric insulators are widely used in newly constructed systems and to replace porcelain and glass insulators in existing power lines due to its improved performance. This paper presents an experimental work, which was carried to evaluate the flashover voltage (kV) of Silicone rubber / Ethylene propylene diene monoemer blends of outdoor insulators.(More)
_ This paper focuses on studying the improvement in the performance of Ethylene Propylene Diene Monomer (EPDM) which is used as outdoor high voltage insulating material by adding ATH filler. The study undertakes an investigation of the dry band arcing characteristics of the composite under un – aging condition. Also the dry band arcing characteristics of(More)
