In the socialist coal industry - one of the highly mechanized and electrified sectors of the national economy - the reduction of losses and savings of electrical energy can reach enormous proportionshus, for example, as a result of increasing the power factor by centralized compensation (artificially), as well as the removal of overestimated capacity of electric motors and transformers in the Ministry of Coal Industry, there were savings of 25.6 million kWh in 1950, and in 1952 - 74.4 million kWh of electricity.
