Power System Harmonics and Passive Filter Designs [Hardcover]

As new technologies are created and advances are made with the ongoing research efforts, power system harmonics has become a subject of great interest. The author presents these nuances with real-life case studies, comprehensive models of power system components for harmonics, and EMTP simulations.

• Comprehensive coverage of power system harmonics
• Presents new harmonic mitigation technologies
• In-depth analysis of the effects of harmonics
• Foreword written by Dr. Jean Mahseredijan, world renowned authority on simulations of electromagnetic transients and harmonics
