Electrical measuring transducers for converting AC and DC electrical quantities to analogue or digital signals (IEC 85/748/CDV:2021); German and English version prEN IEC 60688:2021
Abstract
This International Standard applies to transducers with electrical inputs and outputs for making measurements of AC or DC electrical quantities. The output signal may be in the form of an analogue direct current, an analog 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 following electrical quantities such as: current, voltage, active power, reactive power, power factor, phase angle, frequency, harmonics or total harmonic distortion, apparent power to an output signal. This standard is not applicable for: instrument transformers that complies with IEC 61869 series; transmitters for use in industrial process application that complies with IEC 60770 series. performance measuring and monitoring devices (PMD) that comply with IEC 61557-12. Within the measuring range, the output signal is a function of the measurand. An auxiliary supply may be needed.
