Vliv třídy přesnosti měřících transformátorů proudu na fakturační údaje

Abstract

The bachelor's diploma thesis aims on gauging of the energy consumption by high voltage industrial consumers with indirect measurement method. Consumption data obtained from electrometer are used in the invoicing process in calculation of regulated fees related to electricity supply. The aim of the thesis is to find out how accuracy class of the measuring current transformers can influence obtained consumption data. In chosen supply point launched to the high voltage transmission line was a second set of measuring current transformers placed parallelly to the billing measurement. This set was of inferior quality class in terms of measurement accuracy to the original measuring current transformers used in invoicing. Both sets of obtained data were compared and the difference in final price for regulated fees related to electricity supply was calculated.
