14、-2:1993 ii BSI 12-1999 National foreword This Part of BS 7494 has been prepared under the direction of the Power Electrical Engineering Standards Policy Committee. It is identical with IEC 834-2:1993 Performance and testing of teleprotection equipment of power systems Part 2: Analogue comparison sys
15、tems published by the International Electrotechnical Commission (IEC). In 1995 the European Committee for Electrotechnical Standardization (CENELEC) accepted the text of IEC 834-2:1993, with common modifications, as Harmonization Document HD 543.2.S1. The Technical Committee has reviewed the provisi
16、ons of IEC 255-4:1976, IEC 255-6:1988 and IEC 834-1:1988, to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. There are no equivalent British Standards. A British Standard does not purport to include all the necessary
17、provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
