¿µ¹®³»¿ë¿ä¾à | The necessity of the separate distance between independent earth installations is
due to the dangerous effectiveness of rising potential on the telecommunication earting site by conductive coupling through the earth resistivity. This standard provides the basic calculation method for separate distance between independent grounds and explains the practical application method for parameters included in that formula. And it specilaizes the separate distances between power installations and telecommunication cable. In addition, this standard provides subsidiary applications of countermeasure for personnel and service, installations protection that could not be covered by the separate distance. |
