Earthing, Bonding and Cable Layout
In this chapter the concepts related to earthing and bonding as well as to cable to cable coupling and segregation are briefly reviewed, with extensive reference to Chap. 7 for basic theory and formulas. It is however underlined that earthing, bonding and cable layout in a railway system are to be specified for different subsystems and different types and categories of equipment, while taking into account possible variable system conditions and coping with the needs and requirements of electrical safety, equipment protection, signal reference for correct equipment operation, and interference mitigation. Reference is made to applicable standards with respect to the involved equipment and subsystems, aspect of the railway installation or specific phenomenon.
