The Magnetic Fields module in Cable HV Software calculates the magnetic field intensity in micro Tesla µT occurring around a cable, circuit or a group of circuits. The calculations are based on the Biot-Savart law which explains the fundamental quantitative relationship between and electric current which is flowing and the magnetic field it produces.
The touch and step voltages associated with an earthing system are directly proportional to the magnitude of the fault current flowing into and directly discharges into the soil by the earthing system. Therefore, it is important to determine how much of the fault current returns to remote sources via the cable screens or the overhead earth wires of the lines feeding the substation.

SafeGrid can model custom earthing arrangements of any size or shape in 2D or 3D. You can specify the grid using the in-built editor tools or you can import grids drawn in AutoCAD.
The PDF underlay tool is an addon to the Display Results module of SafeGrid. This tool allows you to overlay the surface, touch or step voltage plots on your site drawings.
