INTERFERENCE MEASUREMENTS

The disruptive effect of the earthing contact of a 50 Hz three phase current open line and of a 16 2/3 Hz railroad contact wire on telecommunications equipment. Disturbance parameters such as inductive current, interference voltage, interference current, mutual coupling, reduction factors, effect of earthbed, and metal components, are examined. Amounts of interference are also to be expected in the telecommunications field in respect to the cable sheathing reduction factor, earth transfer resistance, effect of the terrain and the dissymmetry and sensitivity factor of the telecommunications equipment.
