Silicone rubber (SR) and polymethylmethacrylate (PMMA) are widely used as insulators. To ensure the safe and stable operation of electrical equipment, it is very necessary to study the flashover performance of insulating materials. In this paper, the surface flashover characteristics of SR and PMMA under atmospheric pressure were studied by using the bar-bar electrode and pin-pin electrode, which...
The magnitude distributions of filament current in dielectric barrier discharge were investigated under different supply voltage, barrier thickness and gap size. The experiment was carried out using two planar electrodes powered by 5 kHz and 2 kV power supply. One filament current could only affect a small space in the discharge gap. The number of filaments occurred depended on the rise rate of the...
High voltage impulses and plasma impulses, with durations in the range of a few tens of nanoseconds to a few hundred microseconds, can be used to generate electromechanical stresses in biological membranes, in order to facilitate cell lysis. Modelling and analytical evaluations of the PEF treatment process are introduced in this paper. Simulation of the transient electrical processes in a cell, located...
