| Title | Test of insulation of bars and coils of high-voltage machines |
| Project Number | 5919 |
| Abstract/Scope | This specification applies to rotating electrical machines with rated voltages (Un) from 5 kV to 24 kV inclusive and with rated output from 5 MVA upwards and from 5 MW upwards for motors Requirements for machines with rated voltage above 24 kV should remain the subject of individual agreement This specification is also applicable to machines with rated outputs between 1MVA( 1MW) and 5 MVA(5MW) and with rated voltages of 5 kV and above, provided its use has been agreed beforehand In the case of machines whose windings are cured in the stator, tests on the separate winding elements are not possible; for these machines the requirements in Part B apply. The test of the conductor lamination insulation must however be carried out in accordance with 23 of Part A of this standard |

| Normative reference (6) |
(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Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn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.
