Use of statistical analysis methods in processing population survey data

The article analyzes the structures of measuring channels electricity metering systems. It is shown that such a structure determined by types instruments used and scheme their connection, in particular, meters installed at points. Moreover, counters can have pulse or interface information output. path for includes circuit consisting current voltage transformers, an meter, communication lines, device data collection device. applied method based on standardization metrological characteristics individual elements synthesis entire system. To calculate total error channel, formula takes into account only errors circuit. recent years there has been tendency when transformers and, accordingly, operate mode low loads. In this case, are poorly studied. graphs depending load currents given. values vary with magnitude region negative values. Therefore, wrong choice lead to significant underestimation electricity. depend mainly secondary winding do not significantly affect error. resulting transformer - meter area loads A change leads serious losses (underpayment electricity). automation metering, changes presented, which serve as basis correcting paths.
