Description

Measuring transducers for active power Alternating current and 3-phase current

Application
The measuring transducers Pw-MU, Pnz-MU, Pz-MU, Pd-MU and Pdr-MU are used for the transformation and isolation of the active power in alternating current or three-phase power systems into an impressed direct current and direct voltage signal.

Function
The parameters to be measured are transmitted to the analog multiplier via internal current transformers and voltage dividers. The instantaneous values of current and voltage are then multiplied and formed as the mean value of a direct voltage matching the active power in a downstream integration stage. Sinusoidal and non-sinusoidal alternating current parameters of any waveform may be measured. The galvanic isolation between input and output signals is done using optocoupler. A downstream amplifier supplies the impressed direct current and direct voltage signals. Both outputs are no-load proof and short-circuit proof. Connecting the two outputs is not permissible.
An auxiliary voltage is required for „live zero” or rated voltage flucuations >± 20%.
