Electrical Measuring Transducers for Converting a.c. Electrical Quantities to Analogue or Digital Signals - Edition 2.2; Edition 2: 1992 Consolidated with Amendment 1:1997 and 2:2001
 N 60688

Annotation

This International Standard applies to transducers with electrical inputs and outputs for making measurements of a.c. electrical quantities. The output signal may be in the form of an analogue direct current or in digital form. In this instance, 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 alternating electrical quantities such as:

– current

– voltage

– active power

– reactive power

– power factor

– phase angle

– frequency

to an output signal.

Within the measuring range, the output signal is a function of the measurand. An auxiliary supply may be needed.

This standard applies:

a) if the nominal frequency of the input(s) lies between 5 Hz and 1 500 Hz;

b) if a measuring transducer is part of a system for the measurement of a non-electrical quantity, this standard may be applied to the electrical measuring transducer, if it otherwise falls within the scope of this standard;
