This guide does not discuss the grounding of some applications. For example, grounding of gas insulated substations and metal clad switchgear is not discussed in this guide; the reader will find these topics addressed in IEEE Std 242. The grounding of circuits of core-balance CTs is also not discussed in this guide. The reader can also find this information in IEEE Std 242. Another issue that is not discussed in this guide is the practice of using separate safety and control grounds. For discussion on this topic, the reader is directed to IEEE Std 665.IEEE Std C57.13.3-2005 Electric currentsStandardsElectric currentsGroundingElectric currentsStandards.Electric currentsGrounding.662.20289NjHacINjHaclDOCUMENT9910135338903321IEEE Std C57.13.3-2005 (Revision of IEEE Std C57.13.3-1983)3647474UNINA
