New Methodology for Analysis and Diagnosis of Sympathetic Interaction of Inrush Currents in Power Transformers for Detecting Abnormal Operating Conditions
(IEEE, 2007)
This paper presents a methodology for fast detection and identification of abnormal conditions in electrical systems. Modeling and simulation of most common operations of the system are simulated to create a database ...
Detection and isolation of current-sensor and open-switch faults in electric traction drives
(Institute of Electrical and Electronics Engineers, 2021-08)
In this work, a strategy for detection and isolation of current-sensors and open-switch faults in electric traction drives is proposed. An induction motor drive with only two current sensors is considered for the design ...
