Title Electrical measuring transducers for converting A.C. and D.C. electrical quantities to analogue or digital signals
Project Number 23283
Abstract/Scope IEC 60688:2012 applies to transducers with electrical inputs and outputs for making measurements of a.c. or d.c. electrical quantities. This International Standard is intended to specify the terminology and definitions relating to transducers whose main application are in industry; to unify the test methods used in evaluating transducer performance; and to specify accuracy limits and output values for transducers. The output signal may be in the form of an analogue direct current, an analogue direct voltage or in digital form. In this case, that part of the transducer utilized for communication purposes will need to be compatible with the external system. This standard applies to measuring transducers used for converting electrical quantities such as current, voltage, active power, reactive power, power factor, phase angle, frequency, harmonics or total harmonic distortion, and apparent power to an output signal. This standard is not applicable for instrument transformers that comply with IEC 60044 series; transmitters for use in industrial process applications that comply with the IEC 60770 series; performance measuring and monitoring devices (PMD) that comply with IEC 61557-12.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
