12 11. GROUNDING(Earthing) 12 Definition To make an electric connection between electric devices and the ground Purpose To avoid lightening and static electricity To prevent Over flow of electricity or Over Voltage Stable system operation Cable Grounding Ground Loop No Ground Loop Grounding Point Ground Loop n No Current Path, No Ground Loop n Improper Cable grounding Ground Loop is being built - Potential difference in Ground flowing into Shield line Move to the communication line Electric Noise Proper Cable grounding Ground Loop is not built - Protected from the noise around the cable Grounding Point - Earth : Great - Chassis : Good - Power : Normal 12
