Question:
During the overloading test on the transformer according to § 15.3.2 the temperature of the windings and
their resistance increase and consequently the overload current decreases. Has the fuse current be
readjusted to the original overload current during the test or no adjustment has to be made?
Decision:
The fuse current has to be kept constant during the test.
