The following guidelines should be observed when grounding a cabinet: An unpainted earth reference plane or rail must be installed on the floor of the cabinet for the conventional reference potential. The cabinet was “grounded” to the system neutral—but not properly “earthed” to the soil electrode system. The practical takeaway: Industrial electrical cabinets require BOTH proper grounding (for signal reference and circuit operation) AND earthing (for safety and fault protection). Confusing these. For systems with 110kV and above, where the neutral point is effectively grounded, the metal sheath of single-core cables should be directly connected to the substation grounding device through a grounding switch. At the terminal stations where cables transition to overhead lines in systems of. At the heart of a good grounding scheme is the ground bus bar: a solid, low-impedance conductor that ties all equipment grounding conductors (EGCs) together and connects them to the grounding electrode system. All metal parts of the cabinet are connected with each other. In the fixing of foundation steel, level and total station are utilized for repeated.
