High Voltage Magnitude Measurement from Corona Sound by using Neural Network Suna Bolat Sert Özcan Kalenderli Department of Electrical Engineering Department of Electrical Engineering Istanbul Technical University Istanbul Technical University Istanbul, Turkey Istanbul, Turkey bolats@elk.itu.edu.tr ozcan@elk.itu.edu.tr Abstract— This study presents measuring the magnitude of There are lots of studies in the literature using acoustical voltage applied on a HV line without any physical contact methods. These methods are used for detecting and locating with the line by neural network using corona sound data partial discharges within power transformers [2] and finding as input of the network. Corona sound data used in this radio inference sites caused by discharges associated with high study are acquired from an experimental set-up when voltage power lines [3]. More recently, acoustic methods have applying 50 Hz AC high voltage at different levels to the been used to detect discharges in high voltage compressed gas line conductor. Recorded sound data of corona and the insulated transmission systems [4], monitor discharges in high voltage capacitors, detecting faulty insulation in high voltage voltage magnitudes are applie
