PROCEDURE ESTABLISHING DEPTH OF LAYING OF ELEMENTS OF GROUNDING CIRCUIT Russian patent published in 2004 - IPC

FIELD: instrumentation, determination of depth of laying of elements of grounding circuit of power supply objects and railway traction substations. SUBSTANCE: in correspondence with invention measurement of intensity H₁ of electromagnetic field on ground surface is conducted with the help of first pickup of intensity of electromagnetic field, intensity H₂ of electromagnetic field above ground surface is measured by second pickup of intensity of electromagnetic field rigidly anchored above first pickup at known distance a. Depth of laying of horizontal elements of grounding circuit is found from expression h = a/(H₁/H₂-1). EFFECT: necessity of orientation of pickups in space is excluded which diminishes time and labor input to realization of procedure. 1 dwg
