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...
The sound pressure level (SPL) has been generally accepted in the measurement and evaluation of degree of nuisance to the corona-generated audible noise from transmission lines. Quite many scholars have studied the spectrum and statistical characteristics of the SPL from transmission lines through the long-term frequency measurement. In fact, the corona sources on the transmission lines usually act...
