Note 1 of clause 14.2 states: “ In the case of transformers with a protection index IP00, the temperature of) \' @/ X r) O. B
the support is measured, but the values given in Tables 1 and 3 are not considered”.. j/ K: x% N0 U
Does this mean that the temperature of the support must always be given in the TRF as an informative value?

Yes.
