PPT-Earthing

PRESENTATION BY Er Satnam Singh LecturerElectrical engg GPC Mohali Khunimajra Concept of Earthing Systems All the people living or working in residential commercial and industrial installations particularly the operators and personnel who are in close operation and contact with electrical systems and machineries should essentially be protected against possible electrification . Many such high voltage c ables have metallic sheaths or screens surrounding the conductors andor armour and metallic pipes surrounding the cables During earth fault applied to directly earthed systems these metallic p aths are expected to carry a s CABLE LUGS APPLICATIONTermination of positive, negative , test and reference electrode cables.Bell Entry Copper Tube TerminalsPart No Connect To The Earth & Heal. emfx. A discovery. A former electronics expert claims to have found proof that the Earth can indeed heal us – in a very basic and literal way. He has taken a remarkable journey that began with a bad tooth and just might end in a radical new way for the World to think, live and deal with chronic pain and disease. . Earthing Necessity – – pipe earthing and plate earthing – materials required - requirements of good earth electrode – neutral wire – difference between neutra Earthing. D.K.Pathirana. Applications of . earthing. • Protect human against lightning and earth fault condition. • Protect the premises against lightning and earth fault condition. • Provide low resistance and safe path for lightning and fault current. THE HISTORY OF EARTHING Between 1880 and 1920, transmission and distribution of electrical power took place with unearthed neutrals No points of the network were deliberately earthed.
