【正文】 Hall effect. The block diagram of the acquisition system is presented in and presents the experimental results. Remark: The voltage values and the parameters of the consumers in fig. 3a, were introduced into the application realized for simulation (). 3. Power Measurement in ThreePhase AC Circuits For a random receiver (Z), consisting in linear impedances, forming a system with n nodes which is alimented through a circuit with n conductors [1], the total plex apparent power (S) transmitted to the receiver is: By expressing the potentials of the nodes using the potential differences reported to a point N having a random potential, the expression () bees: (14) The definitions of active and reactive power give the following results: The total active power P (respectively the reactive power – Q) consumed by a random receiver with n phases and alimented through a line of n conductors, is equal to the sum of n active singlephase powers (or reactive singlephase powers) which are given by the Ik line currents, with the UkN voltages between the n conductors and the N point. The alternative threephase circuits have the following voltage system: If the voltage system supplies a threephase balanced receiver, the current system will be: If the phase impedances are different, the receiver is not balanced and the absorbed currents from the source can be calculated with methods that are related to star connected threephase balanced receivers, it results: Regarding the impedance value of the neutral conductor (Z0), the voltage value will be: . Data Acquisition System – block diagram The block diagram of the data acquisition system is presented in . The measuring methods for active/reactive power in threephase ac circuits, depend on the type of the consumer and the number of conductors in the electric energy supply system. For threephase circuits with neutral conductor (n=4), the generalized theorem bees: The total active power in this case can be measured by using the 4 wattmeter method (if a random value is given to the potential of the N point) or using the 3 wattmeter method (if the potential of the N point is equal to the one of the neutral conductor). . Data Acquisition System –experimental results 4 Conclusion The implementation of the applications (simulating and data acquisition) into the LabVIEW graphical programming environment has been realized basing on theoretical aspects and experimental determinations in the laboratory, using accurate devices. These applications can be used both for studying the measurement methods of power (student/personnel training because of the ability of modifying the parameters of the circuits and of the effect display) and for performing high accuracy measurements. The use of the presented signal conditioning system enlarges the data acquisition abilities in the electric system, in order to study the operation of electric machines, converters, transient rates. The flexibility of the instrument is given by the possibility of including other operations in the measurement process (analysis, operation automation, access to the data basis, sending data on the Inter, etc.).
