Earthing Layout Drawing

Product Description

We prepare earthing layout drawings of extra high voltage substations as per the approved earthing calculation of the switchyard. The drawing shows the layout of the earth mat, mat spacing, BOQ and specification of earthing materials. Such drawings are prepared for each of the substation projects designed by us.

We have done earthing layout drawings, calculations and earthing details for many Substations, misc. industrial units in India and abroad for many years and hence gathered extensive experience for supply of these technologies. Our engineers are highly skilled in preparation of Earthing drawings.

Earthing of non current carrying metallic parts of all electrical equipment and building steel structures are required to avoid shock hazards and to provide a return path for flow of earth fault current for operation of earth fault relay. Generally an earth bus is run along the cable tray routes and a ring is formed in all floors of industrial plant buildings. The earthing leads of all electrical equipment are connected to this earth ring at two places.
