SCALE MODEL GROUNDING SIMULATOR FOR GROUND POTENTIAL RISE ANALYSIS

摘要

The present invention is a hemispherical water tank containing a solution; A test grounding system installed in the tank but reduced in proportion to a shape, position, and size of a ground electrode of a real scale; A power supply device for applying AC power, which is a fault current, to the test ground system; A probe capable of horizontal movement on the hemispherical water tank but detecting a potential of the virtual earth surface flowing through the test ground system in contact with the solution contained in the water tank; And a control measuring device for measuring a ground voltage for each distance by measuring a horizontal movement control of the probe and a fault current flowing through the test ground system through a probe; By configuring the position control part of the potential detection probe and the automatic measurement system for automatically measuring the ground potential rise according to the current inflow, the shape of the equipotential surface generated when the current flows to the grounding system appears to be the same as the actual ground network. This provides a ground simulation system for earth potential rise analysis, which enables modeling and accurate analysis of earth potential rise due to fault current inflow.
