Method for increasing the accuracy of energy quality parameters measurement
This paper discusses the energy quality monitoring. A Hall sensor is proposed to use as a transducer. The definition of the hardware function is based on the assumption of a steady-state distribution of the current density. The current density distribution is found to be potential. The instrument function of the transducer for the energy quality determination has been calculated. The results of modeling for the Hall sensor potential distribution are given. The influence of the signal characteristic and the geometric dimensions of the sensor on the instrument function is studied. Recommendations of choosing the number of terms in the series depending on the potentials distribution modeling error are given. Conclusions are drawn about the extremum form for the hardware function of an ideal point sensor.
