Laser Initiated Conduction of an Overvolted Liquid Dielectric.
Abstract
A focused, Q-spoiled laser, aligned along the inter-electrode axis of a pulse charged switch assembly, was used to initiate the conduction of an overvolted transformer oil gap. Laser power varied between 5 and 200 Mw and the voltage pulse exhibited a risetime of 500nsec to a voltage of 700kv. A parametric study of the factors affecting the delay between the laser pulse arrival at the gap and conduction of the gap was accomplished, in which the effect of the laser focal point location and power, polarity and voltage on the gap at laser arrival, was determined.
