a motor's measured current is 45amp,whereas the rated
current is 38 amps but still it is running ,how?
Answer Posted / sabnavees
The motor is running due to the non operation of the thermal
over load relay. The motor will keep on running till the
winding temperature increases the designed limit, finally
the motor will burn under the winding short circuit
condition causing production loss & down time .
