scope:
This section of IEC-34-18 gives test procedures for the thermal evalution and classification of insulation systmes used or propsed for use in a.c. or d.c. rotating electrical machines up to and including 50 MVA and 15 kV using form-wound windings. The test procedures are comparative in that the performance of a candiate insulation systme os compared to that of a reference insulation system with proven service experience.
Section 31 shall be used in conjunction woth Section 1.
NOTES
1 At the present time limited experience exists on insulation systmes above 6,6 kV, using the test procedures given in this section.
2 Large machines, especially those using bars, may require special thermal evalution test procedures which are not included in this section.
