Current instabilities in the farm of randomly occurring pulses are a problem encountered by all who endeavour to produce current-voltage characteristics of a liquid insulant. These pulses signal the impending electrical breakdown of the system unless precautions are taken. In addition to an intensive cleaning of the system and filtration of the liquid entering the test cell the usual procedure is...
The electrical breakdown of liquid dielectrics involves the generation and growth of a vapor cavity [1,2] and the dynamics of these pre-breakdown cavities in low-viscosity fluids have been widely studied photographically through the use of pulsed schlieren and shadowgraph techniques. Hakim and Higham, Farazmand, and Chadband and Wright [31, were the first to publish schlieren photographs that optically...
1. The loss of phenyl methyl silicone oil consists of dipole loss, space-charge loss and ionic conduction loss. 2. A specific loss peak of phenyl methyl silicone oil appearing at 10kHz below −40°C is not likely due to resonance absorption arising from the rotations and vibrations of atoms or ions in the crystal lattices.
