A platform for multiple DC corona effects measurements and analysis

This paper describes a platform for measuring the multiple DC corona-generated effects, i.e. audible noise, ionized fields, ion current density and steady corona current simultaneously. The platform includes the corona cage for generating the corona discharge, the corresponding measuring equipment for each corona effect, and the acquisition and analysis system based on LabVIEW. The system can acquire four channels of signal simultaneously with maximum sampling rate 100kS/s. The processing of the measured signals is performed based on the LabVIEW. Based on this platform, some experiments were conducted and some results are presented in this paper.
