Differential Relay Protection for Prototype Transformer
Published by Bashar M. SALIH, Mohammed A. IBRAHIM, Ali N. HAMOODI, Northern Technical University Abstract. This paper represents the differential protection relay that used to protect the prototype-Terco power transformer. Matlab/Simulink is used to simulate the protection system. The power differential protection algorithm has been simulated and tested on a 2KVA power transformer under differentContinue reading “Differential Relay Protection for Prototype Transformer”
Inter-Turns Short Circuits in Stator Winding of Squirrel-Cage Induction Motor
Published by Maciej ANTAL, Wrocław University of Science and Technology, Department of Electrical Machines, Drives and Measurements Abstract. A physical model of a squirrel-cage induction drive, allowing to stimulate coil short circuits in the front part of the motor, was used to investigate the phenomena accompanying short circuits. Assuming that a short circuit occurs duringContinue reading “Inter-Turns Short Circuits in Stator Winding of Squirrel-Cage Induction Motor”
Accurate Fault Detection and Location in Power Transmission Line Using Concurrent Neuro Fuzzy Technique
Published by Patrick S. Pouabe Eboule, & Ali N. Hasan, University of Johannesburg, South Africa Abstract. In this paper a new approach for the detecting and locating different kinds of faults on power transmission lines using the concurrent neurofuzzy technique (CNF) is introduced. This approach relies on the advantages of combining fuzzy logic (FL) andContinue reading “Accurate Fault Detection and Location in Power Transmission Line Using Concurrent Neuro Fuzzy Technique”
