The purpose of this paper is to review new or improved methods related to generator ground fault protection. Established stator ground fault protection schemes as referenced in IEEE Guides C37.101-2006 and C37.102-2006 are proven to be effective under the most common failure modes but may fall short in detecting faults that develop due to arcing faults or via uncommon mechanisms such as broken conductors. This paper discusses the limitations of existing protection schemes and presents several new approaches that could be considered to complement traditional ground fault protection schemes in high impedance grounded generators.
