CYMGRD for Windows assists engineers to design grounding
facilities for substations and buildings. The program
can be used to perform soil resistivity measurement
interpretations, elevation of ground potential rise and
danger point evaluation within any area of interest.
The program supports soil resistivity analysis taking
into account field measurements, an analysis necessary
to arrive at a soil model that will subsequently be used
for the analysis of the potential elevations. The module
supports either the determination of a "single-layer"
soil model or the data can be interpreted to result in a
"two-layer" soil model. The same module also computes
the tolerable Step and Touch Voltages per IEEE Standard
80, 2000. The user defines the prospective fault current
magnitude, the thickness and resistivity of a layer of
material (such as crushed rock) applied to the soil
surface, the body weight and the anticipated exposure
time.
CYMGRD is capable of performing ground potential rise
calculations and to determine the equivalent resistance
of ground grids of arbitrary shapes, composed of ground
conductors, rods and arcs since it employs matrix
techniques for resolving the current distribution to
ground. Directly energized and/or passive electrodes,
not connected to the energized grid, can be modeled in
order to assess proximity effects.
