Each software package consists of a combination of several modules as detailed in the table.
This software enables the design of grounding for substations, power plants, factories, and buildings. The design can be for uniform or two-layer horizontal soils and calculates touch and step voltages according to IEEE standards.
For grounding system calculations of solar power plants, considering that panel structures are part of the grounding system, calculations differ somewhat from typical substation grounding.
This software receives fault current magnitude and duration, soil thickness, soil resistivity, and body weight from the user and performs the following operations using soil, network, and diagram modules:
Soil Module
Measures soil resistivity based on one or two-layer models. This module can plot measured and calculated resistivity and compute maximum virtual touch and step voltages according to standards.
Network Module
Calculates current released by each conductor into the soil and determines soil surface potential using these currents. The grounding network can be defined as a single conductor or a set of conductors connected in a square. Substation layout can be drawn in 2D or 3D. Underground pipes and adjacent grounding networks can also be considered to see their impact on fault current and surface voltage.
Diagram Module
Summarizes soil resistivity and surface potential analysis results on the display and uses 2D and 3D colored shapes for better presentation.
Key features of CYMGRD software:
Grounding system design for low frequencies (especially substation grounding design according to IEEE 80-2000)

Calculating appropriate cable size in various projects is one of the most important engineering tasks, often done manually. If the selected size is smaller than needed, cable damage or system malfunction may occur; if larger than necessary, despite proper function, economic design is compromised. Designers usually calculate cable size based on voltage drop and short circuit criteria, neglecting thermal sizing. For thermal sizing, especially in MV and HV cables, cable construction and layer specifications must be precisely modeled, and allowable current calculated based on installation environment such as underground, air, tunnels, ducts, trenches, etc. This course uses the professional cable sizing software CYMCAP to familiarize you with cable aspects, steady-state sizing, transient sizing based on current profile, estimation of temperature field around cables, calculation of magnetic flux density, induced voltage on shield, optimizing cable arrangement in duct banks, cable impedance matrix calculation, etc., based on IEC60853, IEC 60287, and Neher-McGrath methods.
