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.
A Signal Ground is the common or return line for any signal. Typically it's the same as the Circuit Ground. A Circuit Ground is the signal common (return) connection for all the devices in a circuit. It's just a convenient reference point. Typically in a circuit you have one or more power points and a Circuit Ground (zero volts) point. It may or may not be connected to earth ground (typically not).
