Substation earthing and exothemic welding

Earthing of a circuit can be defined as physically connecting the circuit with the ground, which was zero-volt potential to the ground (the earth).
The primary objective of substation earthing is to establish a low resistance path for the dissipation of fault currents, lightning surges, and static charges into the earth. As MagCube, we achieve this by creating a network of non-conductive materials that connect the non-current carrying metallic parts of the equipment and the neutral points of transformers and generators to the ground
If properly done, this system plays a critical role in the operation of protective devices such as circuit breakers breakers and fuses. This is important in preventing damage to equipment and minimizing disruption to power supply.

On the other hand, exothermic welding is simply a way of forming high-quality electrical connections and it offers many advantages compared to crimped connections or traditional mechanical bolted connections
The process requires no external power or heat source as it uses the high temperature generated by the reduction of aluminium into copper oxide. The reaction takes place in a graphite mold, machined to the dimensions of the conductors to be welded
