This document provides instructions for a correct installation, use and maintenance of IMEFY SpA cast resin transformers.
a. REFERENCE STANDARDS
b. EU DIRECTIVE AND REGULATION
Directive 2009/125/EC of the European Parliament and of the Council of 21/10/2009.
Commission Regulation (EU) No 548/2014 of 21/05/14.
Commission Regulation (EU) 2019/1783 of 01/10/2019.
c. CE MARKING
CE Marking is affixed in accordance with art. 5 of Directive 2009/125/EC of the European Parliament and of the Council and in compliance with Regulation (EU) No. 548/2014 of Commission of 21 May 2014 concerning the application of Directive 2009/125 with regard to small, medium and large power transformers and following Regulation (EU) 2019/1783 of Commission of 01 October 2019.
IMEFY SpA transformers are fully compliant with above mentioned documents and comply with the requirements of environmental compliance, in addition they are provided with CE marking and declaration of conformity.
d. ELECTROMAGNETIC COMPATIBILITY (EMC)
Cast resin transformers are to be taken into consideration for the disturbance caused by the magnetic field, which is generated by the dispersed flow produced by the current of secondary connections. The magnetic field issued by the windings is moderate and in any case lower than the one issued by the connections, in addition the values of the latter decrease rapidly as the distance from the machine increases. As previously mentioned, cast resin transformers are very often installed inside metal containers or properly screened rooms that reduce the amplitude of the magnetic field by three or four times.
e. CONSTRUCTION DETAILS
The drawing below shows standard construction details of IMEFY SpA transformers.
For non-standard transformers or for more information please contact our technical department providing the serial number of the transformer object of the request.
