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.
While the purpose of grounding is 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. Ground is a source for unwanted currents and also as a return path for main current some times. While earthing is done not for return path but only for protection of delicate equipments.
