- Abstract
The paper presents the implementation method of the EU REGULATION NO. 548/2014 OF THE EUROPEAN COMMISSION FROM 21 MAY 2014 ON THE IMPLEMENTATION OF THE 2009/125/CE DIRECTIVE FROM THE EUROPEAN PARLIAMENT AND COUNCIL REGARDING THE LOW, MEDIUM AND HIGH POWER TRANSFORMERS in the Electrical Energy Distribution Branch Transilvania Nord EDTN, from the technical specification revision and technical documentation preparation, to promoting and achieving upgrading works. This regulation requires a new approach in terms of ecological design requirements for the energetic performance/efficiency of the medium power transformers and high power transformers in comparison to the classical principles: medium power transformers are treated as an "energetic installation with internal services" for which the maximum efficiency index (PEI) is calculated considering the necessary electrical power for the cooling system when functioning without load. High power transformers are transformers with which the 110/MV transformer substations are equipped. In the period 2016-2017 a number of 29 transformers from the transformer substations belonging to EDTN -- Department of Exploitation and Maintenance will be replaced with ecological 110 kV/MV transformers with low losses. The replacement of the existent 110/MT transformers from the transformer substations with the new type of high power transformers is considered to increase the efficiency of the electrical energy distribution activity through: * Losses decrease with 51.3% for the station's transformers * Improvement for the supply continuity indexes, according to the performance standard regarding the energy distribution service Order 28/2007; thus EDTN will have 101 (29+72) 110 kV/MV transformers with their functioning considered to be without risks, namely 49% from the 205 transformers connected to the management installation CEM 110 kV * Costs reduction for maintenance and exploitation
