Methods and Tools of Electricity Metering Information and Measurement System Accuracy Increasing

In the article an error correction method allowing the measurement accuracy 2-4 times increasing is described. It is found that the technical device or methods absence in the information-measuring system for electric power monitoring and accounting allowing taking into account errors and make amendments, reduces the system accuracy that leads to an unreliable estimate of the electricity consumed. The possibility of the structural method of error correction by value is considered in the article. One of the advantage of the structural error correction method is the absence of necessity of replacing the equipment with more expensive ones, and also does not require changing the network structure. A mathematical model of a current transducer with error correction has been developed and the error of the measuring complex without correction and with correction has been calculated. The accuracy figure mismatch of the using equipment was also revealed. The authors offer organizational and technical measures of energy losses reducing.
