Abstract :
IN the standard method for making temperature tests of transformers, the average winding rises are computed from resistance measurements taken after shutdown. This procedure becomes inaccurate when high or rapidly changing temperatures are involved, as in rated-load tests on certain dry-type transformers or in overload tests on oil-immersed apparatus.
