Differential Protection Based on Zero-Sequence Voltages for Generator Stator Ground Fault
Tai Nengling,J. Stenzel +1 more
TL;DR: In this article, a new differential protection scheme based on zero-sequence voltages with 100% coverage for generator stator ground faults is proposed, which exploits the fault information of both the zero sequence fundamental voltage and the third-harmonic voltage.

Wavelets: a new tool for the resonant grounded power distribution systems relaying
TL;DR: The wavelet transform of a signal consists in measuring the "similarity" between the signal and a set of translated and scaled versions of a "mother wavelet" as discussed by the authors.

A Comparison of 100 Percent Stator Ground Fault Protection Schemes for Generator Stator Windings
TL;DR: In this paper, three different schemes for detecting single-phase-to-ground faults in 100% of the generator stator winding are described, and a chart comparing the significant application characteristics of the three schemes is presented.
