Effect of applied field and rate of voltage rise on surface breakdown of oil-immersed polymers
Output of an international research collaboration involving AWE (UK) [Mark.Sinclair@awe.co.uk and ken.thomas@awe.co.uk] and Sandia National Laboratory (USA) [Dr Jane Lehr, jmlehr@unm.edu]. Breakdown along liquid-solid interfaces under short-duration high-voltage pulses limits the energy density of pulsed power systems. A specialist test system operating at 400kV with nanosecond temporal resolution was developed. This allowed the breakdown behaviour along interfaces to be characterised under comparable conditions and using the materials expected for the next generation of high-energy pulsed power machines.
