Measurement System in Underwater Wire Exploding Process

Aim\ Establish a system to study wire exploding underwater. Methods\ Both of the electrical and the optical methods are applyed. A resistance voltage divider is used to measure the voltage waveform of discharging and a current mutual inductor is used to measure the current waveform; A high speed rotating mirror camera is used to take pictures of the shock front; bubble and plasma and pressure sensors are used to measure the water pressure during discharging. In order to avoid intense interference from discharging pulses, many anti disturbances are employed. Results\ An efficient measurement system to study wire expoding under water is established. Conclusion\ A peculiar phenomanon, discharging twice during underwater exploding, is discovered by using the system.
