Description

1-PHASE TRANSDUCER OF POWER NETWORK PARAMETERS

The P41 transducer is a digital programmable device destined to measure and convert of 1-phase power network.

It enables for measurement and conversion of measured quantities into standarised analog current signal.

Quantities measured and calculated by the transducer:

• phase voltage ………………………………………….. U

• current …………………………………………………….. I

• active power …………………………………………….. P

• reactive power………………………………………….. Q

• apparent power…………………………………………. S

• active power factor ……………………………………. Pf

• reactive power factor ………………………………… tg 

• averaging active power (e.g.15 min.)……………. Pav

• Tangent  ………………………………………………… 

• active and reactive energy …………………………. Ept, Eqt,

• frequency ……………………………………………….. f

The transducer has an archive that can store up to 9000 values of a quantity selected by a user, together with time marker.

The transducer stores maximal and minimal values for all measured quantities. Additionally, it is possible to introduce external transmission of measuring transformers which will be taken into account while measuring and calculating of all measuring quantities.

The update time of all available quantities does not exceed

1 second. All quantities and configuration parameters are available through the RS485 interface and USB.

The transducer output signals are galvanically isolated from input signals and the supply. Transducer housing is made of plastic.

On the external side of the transducer there are screw terminal strips socket – plug to which wires of a maximal diameter – 2,5 mm2 can be connected.
