Abstract

Rotating-mirror cameras and oscillographic recording have been used to examine the growth of the leader phase of long sparks in rod-plane gaps under positive impulse potentials. A critical stage is shown to exist during leader development at which its velocity is 1-2 x 106 cm/sec, and where the discharge is halted in the case of no flashover. A theoretical examination is made of the conditions in the leader channel which suggests that a considerable potential gradient exists along its length, particularly when the discharge current is low. Various sources of energy loss are discussed in an attempt to account for the observed leader velocity characteristics. During the later stages of leader development the current, velocity and gap voltage data confirm those reported by previous workers
