Advantages of electrical ground

It is advisable to connect all common grounds together whenever a system has more than one circuit. This ensures that current does not flow from one circuit to the other. In addition, all the equipment grounds should grounded properly and connected to the earth ground.

Advantages of electrical ground

●Providing protection to humans and equipment in case of a fault current in equipment

●Providing a zero-voltage reference point for voltage measurements

●Protection against lightning

●Prevents the build of static charges on material and equipment

●It is a requirement to have a ground system in majority of the electrical circuits. The ground provides safety against fault currents as well as other externally induced voltages such as lightning. The ground point is often assumed to be at zero voltage and is used as the circuit’s zero reference point when measuring voltage.
