Why Attend This Training Course?
Earthing systems provide safety functions by supplying the electrical installation with a low impedance path for any faults in the electrical network. Earthing also acts as a reference point for the electrical source and safety devices to correctly work. Standards concerning earthing have changed, introducing new concepts, design criteria and limit values. It is essential, therefore, that companies remain fully aware of modern practice and the new design tools, measurement techniques and equipment that are available to help engineers. Essentially this training course is broken down into System Earthing and Protective ‎Earthing and Surge/noise protection of power and electronics systems normally found in distribution networks. A brief introduction to the design of substation grounding has been included. Detailed information on ground electrodes and measurement of ground resistance is also available. Course places are limited to ensure high-quality interaction during the practical sessions, presentations and case studies. 

What Is The Training Course Methodology?
This training methodology illustrates the concepts involved in the above areas through practical consideration of actual real-life problems, as well as explanation of concepts by experts in area using video projectors and computer aided case studies based on practical applications. Participants will solve their system problem, where the trainee’s try to apply the skills learnt with guidance from our specialized experts. ACAD will provide participants a comprehensive assessment on the problems solved using the skills acquired in the training course.
