TRAINING ADVANCED ELECTRICAL GROUNDING

Training Grounding Kelistrikan

Training Electrical System

DESCRIPTION

This advanced electrical grounding 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.

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.

WHO SHOULD ATTEND

Electrical Engineers, Project Engineers, Design Engineers, Plant Engineers or those who have a considerable understanding of electrical grounding and are responsible for the engineering, design, construction, installation, inspection, operation, or maintenance of electrical grounding systems in an industrial, commercial or institutional or utility setting.
