On the basis of the resistance model of high voltage electric power metering system, we make a study on the saturation of the measuring CT when the load is heavy. Through experiments on measuring current transformers, we chose high-quality power frequency magnetic core of the least saturation. On the secondary side of the measuring CT, circuit debugging was carried on and through experiments, optimal circuit parameters were determined to optimize the detection circuit which reduced the resistance of the secondary side of the measuring CT to the utmost to decrease the magnetic flux in the magnetic core to weaken saturation. Through FIR filter we extract detection signal from the fault signal to diagnose the fault. The practical test show the extracted detection signal can accurately judge the fault.

Electrical Power Consumption

The article deals with the issue of paying for electricity transmission services by consumers in connection with the introducing on the 1st of July, 2020 the Federal Law no. 522-FZ dated December 27, 2018 and the requirements for smart devices and electricity metering systems. This topic is one of the key points in the fight against non-payments for electrical energy, reducing business losses. The article draws attention to the change in the relationship between a consumer of electrical power and its supplier after the introduction of the above-mentioned law. The opportunities of intelligent electricity metering systems are examined as well as their features and some of their characteristics are given. On the example of the Verkhneuslonsky region of the Republic of Tatarstan, served by the branch of JSC “Network Company” Buinsky electrical networks, a comparative analysis of electrical power consumption is presented according to the data of those consumers who have smart metering devices installed and those who use ordinary counters. It is shown that installation of intelligent electric power metering systems made it possible to increase the useful power supply for the observed period by 15.5% in 2020 against 1.8% when using traditional counters for the same period of 2019.
