Optimalno podešavanje rezolucije registra električne energije pametnog brojila

Technical losses in the transmission network are: of power, i.e. electrical energy, which are a consequence consumption energy for heating elements due to existence active resistance these elements, hysteresis, eddy currents, drain currents insulation, corona and dielectric losses. With most frequent use smart meters indirect connection operation plant set up display electricity from secondary side, will be read on meter screen with an additional error. Then transformation ratios voltage current instrument transformers as 1:1. In order obtain actual value it is necessary multiply measured by transformers. Another way adjust meter, so that megawatts can screen. this paper, errors reading considered, taking into account: measuring transformers, resolutions units electricity, methods setting meters, internal constants nominal electric prescribed maximum registered meter. It investigates how much larger secondarily usual resolution displaying three decimal places unit measurement kilowatt hours compared other possible settings meters. Errors calculation technical high-voltage lines cables power noticeable.
