The Study of Transient Regimes for a Shell-Type Transformer
نویسندگان
چکیده
The transient no-load regime and transient sudden short-circuit regime, of a small power shell-type transformer, will be studied in this paper. Will be determined the current variation in the primary circuit both analytically and by numerical analysis based on finite elements method (FEM). The software used for study is MagNet, developed by the Infolytica Company.

Mitigation Transformer Inrush Current Using Modified Transient Current Limiter
This study presents a modified transient current limiter (MTCL) for mitigation the inrush current of transformers. The MTCL is based on conventional transient current limiter (TCL), which, its configuration is modified to overcome the TCL drawbacks of operation. The proposed MTCL offers lower power losses and voltage/current THD during normal operation mode. It needs only one limiting reactor i...

Nowadays, multi-winding transformers are widely used in traction systems and steel manufacturer. Multi-winding transformer that is used in these systems has especial geometry (that is usually called as split-winding transformer) and encounters with serious magnetic and thermal difficulties. According to the special geometry of split-winding transformer, studding the transient thermal behavior ...
متن کاملTransient Inactivation of Shell Part of Nucleus Accumbens Inhibits and Exacerbates Stress-Induced Metabolic Alterations in Wistar Rats
Introduction: The role of different parts of the extended amygdala in metabolic signs of stress is not well understood. In the present study, we decided to evaluate the impact of the shell part of nucleus accumbens (NAc) on metabolic disturbance induced by electro foot shock stress using transient inactivation method in the rat. Methods: Male Wistar rats (W: 230-250 g) were canuulated un...
