What is difference between system grounding and equipment grounding? System grounding is done by connecting a conductor of a circuit to  the earth to keep the voltage stabilized. Equipment grounding is  when all metal frames of the equipment â¦and conductors are grounded  by a permanent connection.
Grounding means connecting the live part (it means the part which carries current under normal condition) to the earth for example neutral of power transformer. Grounding is done for the protections of power system equipment and to provide an effective return path from the machine to the power source. For example grounding of neutral point of a star connected transformer.Generally Black wire is used for this. Grounding done in the power transmission line for equipment protection from Lightening & Surge.
