Electrical measuring transducers for converting AC and DC electrical quantities to analogue or digital signals

Scope

This document 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.

NOTE The above electrical quantities include AC and/or DC components.
