Smirnov, Sverdlovsky plant of current transformers Current transformer is the first ink in the chain of information and measuring system which includes devices for reception, processing and transfer of data, software and energy meters. However accuracy of all this equipment will not have any sense with the low accuracy of current transformer. For this reason accuracy class of current transformer over the last several years got a peculiar significance. Accuracy class is one of the major characteristics of transformer which specifies that its measurement uncertainty doesnt increase values determined by regulatory documents. And uncertainty in its turn depends on the variety of factors. Key words: current transformer, accuracy class, uncertainty.

Economic aspects of heating and heat supply based on heat hydrodynamic pumps S1 S.V. ozlov Teplo of XXI century OOO The problem of energy efficiency in our country is so sharp that edict of the President of the Russian Federation from June 4, 2008 889 Concerning several measures on increase of energy and ecological efficiency of Russian economics was issued and Energy strategy of Russia for the period till the year 2030 was adopted. Till the year 2030 specific energy intensity of countrys economy should be decreased in 2,7 times. An instrument for implementation of energy strategy will become Federal law 261 from 23.11.09 Concerning energy saving and increase of energy efficiency and alterations in several legislatives acts of the Russian Federation. Key words: heating, heat supply, hydrodynamic pump.
