  • This paper describes the investigation into the actual condition of electrical equipments installation and management for establishing the countermeasures against the electric shock in submerged underground. The investigation was carried out for 27 underground premises in conurbation including Seoul, and potential of the exposed electrical equipments negatively affecting on human safety when disaster occurs was measured. The objects to which measurement was carried out were as follows; electrical source; advertising lighting; power equipment. As a result, it was confirmed that potentials more than 230[V] were induced in some equipments. In addition, the electrical equipments installed in most conventional underground premises were left unmanaged.

  • In this paper an Investigation into the actual condition of electrical equipment installation for the inspection method development based on IEC 60364. The analysis objects are the difference between electrical equipments installation in korea & electrical equipments installation based on the IEC 60364. The measurement elements are loop impedance, operating characteristic of circuit breaker and protective conductor continuance. As a result, the korea electrical equipments installation was almost same the TT system but some different of protective conductor continuance. Electrical equipments installed TN-C-S has noting problem about installation but manager dose not understand about IEC 60364.
