To ensure optimal performance under all possible conditions, it is absolutel
39、y necessary to establish requirements for the apparatus and systems in respect of the different environmental conditions. This section of IEC 870-2 considers all the electrical environmental aspects, i.e. power supply and electromagnetic compatibility (EMC) requirements. The general indications give
40、n in IEC Guides 1)106 and 107 have been followed in the preparation of this section, which has to be considered as a product family standard, based on IEC basic publications. 1 Scope and object This section of IEC 870-2 applies to telecontrol equipment and systems with coded bit serial data transmis
41、sion for monitoring and control of geographically widespread processes. It is also a reference document for teleprotection equipment and systems and for equipment included in a distribution line carrier (DLC) system supporting a distribution automation system (DAS). This standard specifies, with ref
42、erence to the various components of the systems defined above: 1) the characteristics of the power supply to which these components are connected during the normal operation; 2) the EMC minimum requirements, expressed in terms of immunity and emission test levels. With reference to EMC, the test lev
43、els have been selected among the classes established by the IEC basic publications on EMC, taking into account the particular environmental conditions under which the various types of equipment considered by this section operate; test procedures, test circuits and acceptance criteria are briefly ind
44、icated, making reference for detailed information to the IEC basic publications on the various subjects; reference is also made to basic publications on protection techniques and installation practices. 2 Normative references The following normative documents contain provisions which, through refere
45、nce in this text, constitute provisions of this section of IEC 870-2. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this section of IEC870-2 are encouraged to investigate the possibility of applying
