【Abstract】 Based on the coaxial cylindrical structure of pulse transmission line (PTL) of a 0.1 TW pulsed power source, a capacitive voltage divider was designed and inserted in between the inner tube and the outer tube of the PTL. A stainless steel film connecting the outer tube of the PTL and load was designed as pulsed current monitor. The capacitive voltage divider and the current monitor were calibrated on line. The voltage ratio of the capacitive voltage divider was determined to be 418.5 with an accuracy of 4.6% and the resistance of the stainless steel film 1.43 mΩ with an accuracy of 5.1%. The results show that the capacitive voltage divider and the current monitor are ideal probes for measuring high pulsed voltage and current.更多还原
