1   Scope This International Standard applies to transducers with electrical inputs and outputs for making measurements of a.c. or d.c. electrical quantities. 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 the following:

– current,

– voltage,

– active power,

– reactive power,

– power factor,

– phase angle,

– frequency,

– harmonics or total harmonic distortion,

– apparent power

to an output signal . ...
