Porovnání měřicích systémů fakturačního měření v odběrných místech vn při různých provozních stavech DS

Abstract

The presented diploma thesis is focused on measuring sets in three-phase systems that are used for invoicing measurement of electricity consumption in customer supply points connected to the high voltage transmission line. The thesis defines the principles of measurement and their technical and legislative requirements. There are also described various systems of indirect measurement located on the secondary or primary side of the power transformer, their method of connection and comparison of their characteristics. The practical section of the diploma thesis is concentrated on the comparison of different measuring systems in fault conditions in the distribution system. The comparison is made based on the real-life measured data.
