The Role of EHD Processes in the Electrical Breakdown of Liquid Dielectrics
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.
