- b0 J0 ?, q& c. X: \Question: Note 1 of clause 14.2 states: “ In the case of transformers with a protection index
IP00, the temperature of the support is measured, but the values given in tables 1
and 3 are not considered”.
Does this mean that the temperature of the support must always be given in the
9 m8 V- @5 l8 CTRF as an informative value?
Decision: Yes.
