The cabinet room is small; use a branch-centralized type； The cabinet room is large, use a mesh type. For details, see SHT3164 and SHT3081, HGT20513
Refer to Clause 5.3 of SH/t3081-2019
SHT 3164-2021 Preface, “The key points of this revision... specify the grounding system for grid structures”； ……Other types of grounding mechanisms were removed. As I understand it, if this standard is to be implemented, a network structure is necessary.
