| Abstract: | We established a system to study pulsed corona discharge in water. It includes the highspeed photography, electrical measurement unit and pressure measurement unit. The high-speed photography system is composed of GSJ high-speed camera and the Pentazet35 camera made in German. The highest resolving power is 2500k/s and 40k/s respectively. The electrical measurement system includes a high voltage meter, a resistance voltage divider, a sampling resistance and Tektronix THS730A oscillograph. This paper analyses the sensitive equipment, interference source and its origin particularly. The means to reduce the disturbance are introduced. The pressure measurement system is mainly composed of piezoelectrical transducer. |
