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.
Several meanings are applied to the word ground in test & measurement: 1  Signal Ground. A very low impedance return signal path to the circuit under test. 2  Earth Ground. The local zero voltage i.e. the voltage you see when connected to a metal stake in the ground or via a three pin AC power adapter. 3  Ground Reference.
