14.3.2 Temperature-rise test
Question
The independent certification body in Poland "Instytut Energetyki" carries out the testing of
transformers or its inspectors witness this testing at the manufacturers' premises. The
description of resistance measurement during the temperature rise test has caused a dispute
between a manufacturer and the inspector on where exactly the resistance should be
measured. The inspector requested that the resistance be measured on "winding lead exits"
inside the enclosure, while the manufacturer argued for the measurement to be made on
"winding terminals" which in its opinion were the bushings on the enclosure cover.

Subclause 14.3.2.1 General, states:
The winding temperature rise shall be established by the rise in resistance method or
by superposition method. For the determination of the average winding temperature
rise the measured temperatures of the cooling air or of the water intake of the cooling
equipment shall be used.
For three-phase transformers, the resistance measurements
