Explanation for Preparation 1. Subject Content and Application Scope 1.1 Subject content This Atlas is a revision of and replaces the national building standard design 86D563 Installation of Earth Device, with added scheme contents such as various earthing modes for transformer and diesel generator, PE mains laying along cable bridge, use of metal water supply pipe and steel bar in reinforced concrete as earth electrode for PE line. 1.2 Application scope This Atlas is applicable to construction and installation of protective earthing, working earthing, lightning protection earthing installations for general industries and civil buildings. 2. Preparation Basis 2.1 National standards of the People's Republic of China Electrical Installations of Buildings—Part 5: Selection and Erection of Electrical Equipment—Chapter 54: Earthing Arrangements and Protective Conductors GB 16895.3-1997 idt IEC 60364-5-54:1980 Electrical Installations of Buildings—Part 7: Requirements for Special Installations or Locations—Section 707: Earthing Requirements for the Electrical Installation of Data Processing Equipment GB16895.9-2000 idt IEC 60364-7-707:1984 Types and Safety Technical Requirements of System Earthing GB14050-93 Code for Construction and Acceptance of Earthing Connection Electric Equipment Installation Engineering GB50169-92 Code of Acceptance of Construction Quality of Electrical Installation in Building GB50303-2002 2.2 Professional standards of the People's Republic of China Earthing for AC Electrical Installations DL/T 621-1997 Code for the Design of Static Electricity Earthing for Petrochemical Industry SH3097-2000 3. Terminology 3.1 working earthing, system earthing the earthing (e.g. neutral point direct earthing or earthing with other installations) required for operation, in the electrical devices of power system 3.2 protective earthing the earthing for preventing metal enclosure of electrical apparatus, framework of power distribution device, line pole/tower, etc. which may be possibly live due to damaged insulation, from endangering the personnel and equipment safety 3.3 lightning protection earthing the earthing set for discharging the lightning current from the lightning protection installation (e.g. lightning rod, lightning conductor and lightning arrester) to the ground 3.4 electrostatic earthing the earthing set for preventing the static electricity from endangering electronic information system, flammable oil, natural gas tank, petrochemical plant and pipelines 3.5 earth electrode the metallic conductor and conductive module that is embedded in and directly contacts the ground. The metal structure, metal well casing, foundation of reinforced concrete building (structure), metal pipeline and equipment which is used as earth electrode is termed as natural earth electrode.
