BAIJIAN will arrange engineers to confirm the relevant testing content with you before making a quotation
The grounding resistance value for lightning protection is the standard.
Due to different systems specifying different resistance values based on the distribution system and the size of the grounding fault current, the grounding standards for resistors may also vary.
. The following are the standard values for resistance grounding:1. The independent lightning protection grounding resistance should be less than or equal to 10 ohms 2. The independent safety protection grounding resistance should be less than or equal to 4 ohms 3. The independent AC working grounding resistance should be less than or equal to 4 ohms 4. The independent DC working grounding resistance should be less than or equal to 4 ohms 5. The anti-static grounding resistance is generally required to be less than or equal to 100 ohms
