| Title | Evaluation of electromagnetic fields around power transformers |
| Project Number | 16657 |
| Abstract/Scope | This Report provides guidance for the evaluation of electromagnetic fields around power transformers. This Report applies to power transformers covered by EN 60076 series with the following characteristics: - apparent rating P: 5 kVA P 1 000 MVA - insulating level, according to EN 60076-3: • high voltage winding: Um from 7,2 kV to 525 kV • low voltage winding: Um up to 525 kV Reactors are excluded from the present Report. Continuous conducted and radiated emissions are considered for power transformers operating under nominal working conditions of voltage and current. Fault conditions and low occurrence transient events, such as - short-circuits, - lightning and switching transients, - overloads (inrush currents, etc.), - overvoltages, - tap-changer operations, are not considered as normal working conditions. Immunity conditions are considered to ensure the power transformer operates as intended in its normal working environment. The immunity capability of the power transformer is considered for steady state and transient working conditions. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
