| Summary | This standard specifies the technical principles for the selection of neutral point resistance grounding methods for medium-voltage power distribution systems with voltage levels of 6kV to 35kV, as well as the configuration principles for resistance devices and their supporting grounding transformers, current transformers and other equipment. This standard applies to the design of the neutral point grounding resistance of the power distribution system in the new, expanded or rebuilt projects of petroleum refining, petrochemical, and coal-based fuel and chemical products. |
