HUMAN SAFETY GROUND
The enclosure of the equipment and N.G.R shall be connected with the main grid of the grounding system. The low voltage electrical equipments and panels shall be connected to the grounding system by looping fromand panels shall be connected to the grounding system by looping from main grid grounding system. All layers of cable tray and supports shall be bonded every 30 meters.
SYSTEM EARTHING
Th di lt l t i l i t h ll b t d ith lThe medium voltage electrical equipments shall be connected with low resistance grounding system for the protection. The low resistance grounding system shall be formed by connecting the neutral point of the equipment with Neutral ground resistor and the N.G.R shall be connected with individual gground wells.

CAD WELDING
Procedure
The cad weld connection is made by dumping a container of weldThe cad weld connection is made by dumping a container of weld metal copper oxide and aluminum) into a semi permanent graphite mold housing the conductor with a flint igniter. The exothermic reaction produces molten cavity and weld the conductor to pipes.
