• It is important to make clear gas flow distribution in SF6-gas insulated transformer windings because cooling performance of winding depends on gas velocity at each cooling ducts.We try to measure velocity distribution in disc type winding by laser-doppler-velocimeter and make clear velocity distribution characteristics.We estimate velocity distribution by calculation and clarify that difference for velocity distribution between air flow and SF gas flow is about 10_??_15% and that for improvement of inclination of velocity distribution, it is effective to arrange cooling duct size properly.
