Description
IEC 60688:2024 applies to transducers (TRD) with electrical inputs and outputs for making measurements of AC or DC electrical quantities. The output signal can be in the form of an analogue or digital signal.
This document 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,
' apparent power, and
' DC power
to an output signal.
This document applies
a) if the fundamental frequency of the input(s) lies between 0 Hz and 1 500 Hz,
b) to the electrical measuring transducer if it is part of a system for the measurement of an electrical or non-electrical quantity,
c) to transducers for use in a variety of applications such as telemetry and process control and in one of a number of defined environments.
This document is not applicable for:
' instrument transformers that comply with IEC 61869 (all parts),
' transmitters for use in an industrial process application that comply with IEC 60770 (all parts),
' power metering and monitoring devices (PMD) that comply with IEC 61557-12,
' meters that comply with the IEC 62053 series,
' handheld sensors,
' residual current monitoring devices (RCMs) that comply with IEC 62020-1,
' residual current detecting devices (RDC-DD) that comply with IEC 62955,
' in-cable control and protection devices (IC-CPDs) that comply with IEC 62752,
' modular residual current devices (MRCDs) that comply with IEC 60947 2:2016/AMD1:2019, Annex M.
Within the measuring range, the output signal is a function of the measurand. An auxiliary supply can be required.
This document is intended:
' to specify the terminology and definitions relating to transducers whose main application is in industry,
' to unify the test methods used in evaluating transducer performance,
' to specify accuracy limits and output values for transducers.
IEC 60688:2024 cancels and replaces the fourth edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) updating normative references;
b) updating definitions;
c) updating structure;
d) adding DC power measurement.
