The scope of present documents is to identify the best practices for protective earthing for steel, aluminium, mobile or fixed offshore Units and non-metallic vessels.
Protective Earthing is a requirement to divert unwanted, potentially hazardous currents from all exposed metallic parts such as equipment chassis, racks, cabi-nets, cable trays, conduit, and …
Earthing conductors which are defined in BS 7671 as a protective conductor connecting the main earthing terminal of an installation to an earth electrode or other means of earthing must be …
In a typical installation, there will be a protective earth system such as that provided by the mains protective earth conductor. Ideally, interaction between the SPD earth and the protective earth …
The continued protective action of the earthing system must be ensured through regular maintenance and testing. Besides the state of the art and the named standards, the directives …
The earthing arrangement should be sufficiently robust to ensure it lasts the lifetime of the installation, and be protected from mechanical damage and corrosion so that it remains …
Earthing or Grounding is connecting an electrical network, equipment or structure to earth incidentally or intentionally, directly or through a conducting medium.
Earth Leakage Current — A current which flows to earth or to extraneous conductive parts in a circuit which is electrically sound. Earthing Conductor — A protective conductor connecting the …
The earthing of a system or installation is generally provided for reasons of safety. This British Standard applies only to land-based installations in and around buildings.
1.1.1 The scope of these guidelines is to identify the best practices for protective earthing for steel, aluminium or non-metallic vessels and mobile or fixed offshore Units.
