Abstract
Nowadays, in many applications, the Permanent Magnet Synchronous Motor (PMSM) has become an alternative to induction machines due to its reliability and excellent dynamic performance. Therefore, the PMSM are being used in the large variety of applications, especially in automotive or high power traction systems. In this motor, the diagnosis of magnetic status has become a challenging task for many researchers since a decade. Therefore, in this research paper an attempt has been made to solve the above problem and trying to diagnose magnetic demagnetization in the early stage precisely. The magnetic demagnetization of the PMSM has been diagnosed with the help of a proposed simulation model. In the simulation model, various stages of magnetic demagnetizations have been created by varying some physical parameters and have been diagnosed in the early stages by applying advanced wavelet transform technique. For diagnosis of magnetic demagnetization, two approaches have been used; first is the time domain technique and second is the time-frequency domain technique.

Continuous Overvoltage Characteristics of Surge Protected Power Strips

Volume 5 Issue 4 September - November 2017 Research Paper Continuous Overvoltage Characteristics of Surge Protected Power Strips Cengiz Polat* Assistant Professor, Department of Electrical and Electronics Engineering, Istanbul University, Istanbul, Turkey. Uzunoglu, C. P. (2017). Continuous Over Voltage Characteristics of Surge Protected Power Strips.  i-manager’s Journal on Circuits and Systems,  5(4), 1-7.  https://doi.org/10.26634/jcir.5.4.13938 Abstract Increasing applications of constantly developing electronic devices require delicate voltage and current protection. Although the electrical network is monitored continuously, undesired over currents and over voltages may occur on the distribution system due to failures. Most of the electronic switch gear is connected via surge protected power strips in indoor applications, where current protection is vital. Surge protected power strips are usually manufactured based on Metal Oxide Varistors (MOVs) ...

A Review on Control strategies for LFC in Deregulated Scenario

Volume 1 Issue 1 December - February 2013 Review Paper A Review on Control strategies for LFC in Deregulated Scenario T. Anilkumar*, N. Venkata ramana** * Associate Professor, EEE Department, ACE Engineering College, Ghatkesar, Hyderabad, AP, India. ** Professor and Head of Deportment, EEE Department, JNTU Mantini, AP, India. Kumar, T. A., and Ramana, N., (2013). A Review On Control Strategies For LFC In Deregulated Scenario.  i-manager’s Journal on Circuits and Systems , 1(1), 27-36.  https://doi.org/10.26634/jcir.1.1.2197 Abstract In power system studies, Load frequency control is an important issue to supply sufficient and reliable electric power with good quality. The main objective of LFC is to maintain load frequency and tie-line power flow within permissible limits by adjusting megawatt output of LFC generators, so as to accommodate fluctuating load demands. This paper presents a brief review of different control techniques to researchers on design...
