IS 14570 : 2024/IEC 60688 : 2021 Electrical Measuring Transducers for Converting a.c. and d.c. Electrical Quantities to Analogue or Digital Signals
NATIONAL FOREWORD
This Indian Standard (Third Revision) which is identical with IEC 60688 : 2021 'Electrical measuring transducers for converting AC and DC electrical quantities to analogue or digital signals' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Measuring Equipment for Basic Electrical Quantities Sectional Committee and approval of the Electro technical Division Council.
This standard was first published in 1998 and was revised in 2002 and 2012. This revision has been undertaken to align this standard with the latest International Standard of IEC 60688 : 2021.
The text of the IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appears referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker, while in Indian Standards the current practice is to use a point (.) as the decimal marker.
