( Institute of Electrical and Electronics Engineers Inc. , 2022 , Article)This paper addresses the localization of Partial Discharge through a 3D Finite Element Method analysis of acoustic wave propagation inside a 3-phase 35kV transformer with the help of COMSOL Multiphysics software. Due to ... -
Evaluation of a calibration technique in measuring partial discharges inside mineral oils with a high-frequency current transformer (HFCT) sensor: A case study
Besharatifard, Hamidreza; Hasanzadeh, Saeed; Muyeen, S M; Kamwa, Innocent ( John Wiley and Sons Inc , 2023 , Article)Partial discharge is one of the main reasons for insulation degradation in high-voltage apparatuses. Partial discharge is an ineluctable phenomenon that happens when a high electrical field is adjacent to an insulator. ...
