HT motor will rotate at a low speed if 415 v power supply
is given to the terminals of an ht motor. This a a type of
test in which if the moisture is found in the motor then
the same can be evaporated by this method. Moreover, there
is a test called block rotor test in which we can block the
rotor shaft and give the 415 v power supply to terminals
and thus the heating will occur in the winding and thus the
IR value will improve. This has been practically testes by
us at lot of sites....
