Corona discharges in asymmetric electrode configurations

摘要: Abstract The dual electrode, which consists of an ionizing wire in parallel with a metallic cylindrical support, both connected at same high voltage supply, has been extensively studied relation various electrostatic applications. In practical situations, the electrode may be installed proximity objects that will affect electric field repartition and, hence, development discharge. aim present work is to analyze operating conditions such electrodes presence rods or plates fixed floating potentials. Superficial Charge Simulation Method was then employed for numerical analysis several arrangements involving corona and rod it. paper also reports results current–voltage characteristics current density measurements alone other bodies potential. leads increase inception threshold shifts I–V higher voltages. potential reduce discharge very low values, while those energized as simply anneal
