40、SI EN 60870-2-1:1996 BSI 11-19983 Introduction Telecontrol systems are used for monitoring and control of geographically widespread processes and have to work under a wide range of environmental conditions. To ensure optimal performance under all possible conditions, it is absolutely necessary to es
41、tablish 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 given in IEC Guides1)
42、 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 transmission for monitori
43、ng 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 reference to the var
44、ious 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 levels have been sel
45、ected 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 indicated, making re
46、ference 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 reference in this text,
47、 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 IEC 870-2 are encouraged to investigate the possibility of applying the most recent
