Most of Taiwan's industries are small and medium-sized, and there are a large number of small and medium-sized factories and households. The safety of electricity is even more important. However, during the construction of early buildings including computer facilities in Taiwan, only the neutral line grounding (N-phase grounding) was emphasized and the equipment system grounding (G-pole grounding) was often ignored. In the case of the equipment failure, it may cause Information devices to damage data loss and the danger of electric shock, and hence the safety issues are critical and should care. This thesis discusses the improvement of equipment system grounding (G-pole grounding). After investigating various grounding methods and analyzing the advantages and disadvantages, the grounding improvement methods applicable to bungalows, tin houses and early sky roofs are proposed. Finally, real cases are used to verify that the grounding improvement methods of the equipment system proposed in this thesis can effectively improve electrical safety.
