Note 1 of clause 14.2 states: “ In the case of transformers with a protection index IP00, the temperature of/ T6 U& W: [- a" ^9 O, P
the support is measured, but the values given in Tables 1 and 3 are not considered”.
! [2 E7 U" d; a4 ]: LDoes this mean that the temperature of the support must always be given in the TRF as an informative value?

Yes.
