This study investigates the relationship between void size and insulation lifetime due to partial discharges (PDs) in internal voids. Experimental results clearly show that the larger the void size, the shorter the insulation lifetime, which decrease

SUMMARY The vacuum circuit breaker (VCB) achieves the high current interrupting capability in the pressure lower than 10 Pa to 5 Pa. When gas pressure increases, the breakdown voltage of a VCB decreases according to Paschen's law, and in the case of

Enhancement of Cooling Rate During Rapid Quenching of a Thin Horizontal Wire by Ultrasonic Vibration
Publikováno v:
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 62:3943-3949
The effect of ultrasonic vibration on heat transfer during rapid quenching of 0.3 and 0.5mm dia horizontal platinum wires was studied experimentally using water and ethanol as test liquids. The frequencies of ultrasonic vibration ν were 24 and 44kHz
