MALT - Grounding Analysis

 

Technical Highlights

MALT has important features which are unmatched by other comparable programs. For example, you can:

• Apply equivalent soil models with one, two or more horizontal or vertical layers. You can also model soil structures such as spherically or cylindrically layered soils and soils with finite volumes of different resistivities - model substation backfill sites, dams, for example.

Using MALT, you can model vertical and horizontal multilayer soils, cylindrical, sphrerical as well as arbitrary finite volumes of heterogeneous soil

• Specify any number of electrodes whether energized or not.
• Locate conductors arbitrarily in the soil, i.e., you are not restricted to x, y, or z directed conductors.
• Energize each electrode individually with your choice of current and / or voltage sources.
• Interpret ground impedance measurements in non uniform soils obtained using the fall-of-potential method or other techniques.

Technical Features

• Grounding systems are modeled as a network of lossless cylindrical conductors freely directed in space.
• Horizontally-layered soils can have any number of different layers.
• Vertically-layered soils with arbitrary resistivity contrasts and arbitrary orientation of the grounding network with respect to the vertical layers.
• Spherical layers, cylindrical layers and arbitrary, prismatic volumes of soil with any values of soil resistivities can be embedded in the native soil.
• MALT computes the ground potential rise of every independent system of the grounding network, earth leakage current distribution along every conductor segment, and potentials at each specified point in the earth or at the earth’’s surface.
• The grounding systems can be any arbitrary group of metallic structures.  Each structure can be energized or not and can have potential rises that are different from each other.

Using MALT, you can model arbitrary group of metallic structures
