Abstract

The technology to deliver, to the market place efficient, low cost, and reliable thyristors with large stand off voltage and large saturation current capability, has led to nonlinear loads that corrupt the commercial 60 Hertz power distribution system. The authors describe how the combined effects of the switching harmonics, the poor power factor of nonlinear loads and the use of capacitors for power factor correction has led to a phenomenon that creates a transmission line resonance that has led to significant destructive failure mechanisms
