| Abstract: | Conductive coupling,inductance coupling,electromagnetic induction and grounding potential fluctuation etc,were regarded as disturbance sources of DCS. The formation of the above mentioned four disturbance sources was analysized.Several main antidisturbance measures such as grounding,shielding,cableselecting and isolating were proposed.The construction and precautions for the various measures against disturbance were general introduced. |
