Analysis of the transient electromagnetic field in a conducting bushing
Finite Elements in Analysis and Design, 1992Abstract The paper presents a general method for the analysis of the transient electromagnetic field and the calculation of power losses in axially-symmetrical conductors with known boundary conditions. The method consists of the numerical version of the Bubnov-Galerkin method (finite element method) for discretization of the conducting region and ...

Transient electromagnetic analysis in tokamaks using typhoon code
Fusion Engineering and Design, 1996Abstract The transient electromagnetic analysis of conducting structures in tokamaks is presented. This analysis is based on a three-dimensional thin conducting shell model. The finite element method has been used to solve the corresponding integrodifferential equation.

The use of electromagnetic transient programs for voltage sag analysis
8th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.98EX227), 2002This paper discusses some of the modeling considerations when simulating voltage sags, and gives examples of voltage sag studies performed by using EMTP. Component models are discussed for overhead lines, underground cables, induction motors and synchronous generators.

Modeling of UHV power transformer and analysis of electromagnetic transient
2009 IEEE Power & Energy Society General Meeting, 2009To correctly apply transformer differential protection in the environment of UHV (Ultra High Voltage), it is necessary to model the UHV power transformer reasonably and carry out corresponding electromagnetic transient simulations. Therefore, according to the equivalent circuit of three winding auto-transformer, we firstly set up the three winding ...

Power quality analysis using electromagnetic transients programs
8th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.98EX227), 2002Power quality is a subject of great concern for electric utilities and their customers, since disturbances can have a very adverse effect on customer equipment. Several techniques have been developed over the last decades to simulate and analyze power quality problems using a digital computer.

Transient analysis of a D-C electromagnet with cutout switch
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1955This paper analyzes the effect of the armature motion on the force stroke characteristics, the pickup speed, and the interruption performance of the cutout switch of a d-c electromagnet. The analysis of the interruption performance is made for a case where a capacitor is connected across the cutout switch. The same method can be extended to other cases.

Analysis of transient electromagnetic processes in wire antenna systems
USSR Computational Mathematics and Mathematical Physics, 1990Abstract The problems of the correctness and accuracy of the Fredholm integral equations of the first kind which arise when analysing non-stationary processes in thin-wire structures are investigated. Some transients that occur in antenna arrays consisting of unbalanced dipoles are considered.
