Abstract: Detection of partial discharge is an effective way to evaluate the insulation condition of Medium Voltage switchgears. However, traditional sensors have shown insufficient sensitivity in practical applications, especially for the multilayer shielding structure of gas-insulated switchgear. Recently, it has been found that the embedded bushing sensor within the switchgear enables the coupling of PD pulses from high voltage and provides corresponding synchronization signals, demonstrating great potential for partial discharge detection. The aim of this webinar is to introduce a device based on this approach, including its working principle and hardware structure. The effect of signal separation, location and identification of partial discharge based on this device is analyzed. Some real field cases of this device are also described.
Bio: Tao Han (IEEE M’15) received the Ph.D. degree in high voltage and insulation technology from the School of Electrical and Information Engineering, Tianjin University, Tianjin, China, in 2015. He is currently an Associate Professor of High Voltage and Electrical Insulation at Tianjin University. His current research interests include the diagnostic testing of electrical insulation and failure analysis of high-voltage power cables.
Andrea Cavallini (Fellow, IEEE) received from the University of Bologna the master’s degree in electrical engineering in 1990 and the Ph.D. degree in electrical engineering in 1995. He was a researcher at Ferrara University from 1995 to 1998. He is a Full Professor at University of Bologna. He was cofounder of spinoff company Techimp HQ Spa. His research interests are diagnosis of insulation systems by partial discharge analysis, reliability of electrical systems and artificial intelligence. He is author or co-author of more than 280 international papers and holds 16 international patents. He is a member of IEC TC 2/MT 10.
Jin He, graduated from Shandong University with a master’s degree in High Voltage and Insulation Technology in June 2013, is currently the person in charge of the switchgear specialty at the Evaluation Center of State Grid Tianjin Electric Power Company and also a member of the online condition monitoring expert groups of State Grid Corporation of China.
