ABSTRACT

According to the coaxial cylindrical structure of oilline on 1 MV, 30 ns pulsed power source, an annular capacitive voltage divider was designed in the end of the oilline as pulsed voltage monitor. A stainless steel film connecting the outer tube and load was designed as pulsed current monitor. The capacitive voltage divider’s probe and the stainless steel film monitor’s probe were calibrated on line. The results show that the capacitive voltage divider and the current monitor are ideal probes for measuring high pulsed voltage and current.

Keywords:Oilline, Calibrate, Annular Capacitive Voltage Divider, Stainless Steel
