Investigation of Devices for Measuring the Quality of Electrical Energy

Electric energy is the most mass product, as well as the most widely consumed type of energy both in industry and in everyday life. In a modern market economy, it is necessary to improve the quality of manufactured products, including the economical use of fuel and energy resources, the economical use of financial resources, and increased efficiency. One of the parameters of electricity standardized by standards is voltage. The article presents deterministic and statistical methods for determining voltage deviation. Also, a virtual instrument is studied. When measuring with a virtual method, corrective filtration of electrical energy was introduced in each measurement link. This method reduces energy losses, which means that the deviation during transformation does not increase.
