DEEP-EMBEDMENT INSULATION INDEPENDENCE GROUND ELECTRODE, INSULATION DEPTH SETTING METHOD THEREFOR AND CONNECTING METHOD WITH LIGHTNING ROD LEAD WIRE

摘要

PROBLEM TO BE SOLVED: To facilitate comparison with an actual measurement under construction, and to provide an ideal deep-embedment insulation independence ground electrode and a setting method therefor. ;SOLUTION: This deep-embedment insulation independence ground electrode comprises a ground conductor 2, an insulated electric wire 3, a ground electrode part 1, and an insulation part 4 provided between the electrode part 1 and the insulated electric wire 3. A setting method therefor is as follows. In the case that a current I flows into the ground electrode, an earth surface electric potential and its range to an insulation depth (t) and a length (1) of the ground electrode part 1 are calculated, a standard graph is made from the calculation, and an insulation depth of the ground electrode, an isolation interval of the ground electrode, or the like, is compared to the standard graph and set.;COPYRIGHT: (C)2001,JPO
