Example Rolling Sphere Method calculation which shows how to overlay protection systems such as lightning masts and earth wires on a site drawing.
This tutorial shows you step-by-step how to use SafeGrid Earthing Software to perform an earthing design which will show you the design process.
Learn how to calculate the fault currents returning to remote sources via the cable screens or overhead earth wires of substation feeders for an earthing design.
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.
Learn how to use this tool which allows you to overlay the surface, touch or step voltage plots on your site construction drawings.
Provides a worked example of a cable pulling tension calculation where the input cable sections and the tension and sidewall pressure results are explained.
Example study using ABB thermal-magnetic and electronic devices shows how to create coordination curves, adjust settings and determine sequence of operation.
Create a desktop icon for the web app so you can quickly and easily access the software.
How to use the Cable Model Editor to model custom cables from manufacturer datasheets and use the cable model obtain the current-carrying capacity.
An example calculation of 132 kV single core and 22 kV three core cable circuits crossing where the derating factor for variation of the crossing angle is examined.
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.
