The Role of EHD Processes in the Electrical Breakdown of Liquid Dielectrics
- 445 Downloads
Our understanding of the electrical breakdown of liquid dielectrics depends largely on the use of pulsed schlieren and shadowgraph optical techniques to photograph the pre-breakdown events. Experimental work of this type began 35 years ago with the pioneering studies of Hakim and Higham  and of Farazmand , who were the first to publish schlieren photographs that optically resolved pre-breakdown events in liquids. Studies of this type were continued by Chadband and Wright  and many others, and a considerable amount of photographic data of this type is now available.
