Grounding and Earthing, Bonding, Lightning and Surge Arrester

StartFragment

At the end of the workshop, participants will be able to: apply the various methods of grounding electrical systems, detect the applicable national standards, describe the purpose of grounding and bonding, list the types of systems that cannot be grounded, describe what systems can be operated underground, correctly shield sensitive communication cable from noise and interference, apply practical knowledge of surge and transient protection, troubleshoot and fix grounding and surge problems, design, install and test an effective grounding systems for electronic equipment, understand lightning and how to minimize its impact on your facility, protect sensitive equipment from lightning.
