In regard to collisionless heating in inductively coupled discharges, two approaches have been widely adopted describe the energy transfer between electrons and radio frequency field. One approach is based on consistent kinetic theory, by which resulting field can be expressed as superposition of a series plane waves resonant interactions happen each wave, might dominate heating. Another single...

Focusing on the influence of fine metal particles on the insulation characteristics of outdoor insulators, spherical micrometer-level iron powders were used to represent fine metal particles of different parameters on a polymer insulator specimen surface. Dynamic movement and lift-off behavior of fine particles, as well as the triggered surface discharges under AC voltage were investigated in a...

Modern electrical machines employed in transportation applications are required to provide high performance terms of power (and torque) density. At the same time, being these safety-critical, a significant level reliability and/or fault tolerance is expected. Among all factors which can compromise motors reliability, partial discharges (PDs) inception one most crucial, particular for low voltag...

Spontaneous acceleration of ions to suprathermal energies is observed during magnetic reconnection in the Mega-Ampere Spherical Tokamak (MAST). A high-energy tail is observed in the ion-distribution function following each internal reconnection event in Ohmic discharges. This phenomenon is explained in terms of runaway ion acceleration in the electric field induced by the reconnection.

Some fish emit electric fields generated by the coordinated activation of electric organs. Such discharges are used for exploring the environment and for communication. This article deals with the development of the electric organ and its discharge in Gymnotus, a pulse genus in which brief discharges are separated by regular silent intervals. It is focused on the anatomo-functional study of fis...
