Advanced Electrical Grounding

Advanced Electrical Grounding

Our Advanced Electrical Grounding Training Course provides a higher level, more in-depth and comprehensive coverage of the Basic Electrical Grounding Course.

While the Basic Grounding Course provided a simplified coverage of the basic principles of grounding and grounding design, the Advanced Electrical Grounding Training Course will follow by a step-by-step design procedures.

The resistivity and conductivity properties of the soil and the ” analysis of “Distribution of Surface Potentials and Currents” will be presented in the “Basic Geology” session.

More detail coverage includes additional formulas and calculations not presented on the basic course. As an example, calculations for "Ground Fault Currents" will be presented.

This Advanced Electrical Grounding Training course will also address other grounding electrode systems not covered in the basic eletrical grounding course such as “Buried Horizontal Ground Grids”, the “Three-Point” triangular electrode and calculations for determining the area of influence of grounding electrodes, such as a ground rod.

The course will also include additional principles involved in Earth Resistance testing and additional methods of measuring the “Ground Resistance” such as “The Slope Method” grounding resistance testing for large grounding systems such as substations.

Soil characterization is addressed, followed by measurement interpretation.

Modeling requirements and data preparation procedures for substation ground system design will be discussed as well as options for controlling ground potential rise, touch and step voltages.

The lightning protection section of the course will provide as an additional material, calculations for transient over voltage generated in high structures such as transmission and communications towers and the step voltage hazards caused by transient induced voltage gradients in the earth. Capacitive coupling of transient energy will also be discussed.

This course will also provide a comprehensive coverage of design practices for grounding and electromagnetic compatibility of industrial, commercial, and residential systems with linear and distorting loads.

For critical electronic loads, this advanced course will provide grounding practices for signal reference subsystems, multipoint grounding systems and lower and higher frequency signal reference networks, subjects not covered in the basic grounding course.
