Squirrel Cage Induction Motor Testing(LT/Part1)
Type Tests (as per IS 12615) The following shall constitute type tests: a) Dimensions; b) Measurement of resistance of windings of stator; c) No load test at rated voltage to determine input current power and speed; d) Reduced voltage running up test at no load (for squirrel cage motors up to 37 kW only); e) Locked rotor readings of voltage, current, power input and torque at a suitable reduce voltage; f) Full load test to determine efficiency, power factor and slip; g) Temperature rise test; h) Momentary overload test; j) Insulation resistance test; and k) High voltage test. Optional Tests(as per IS 12615) The optional tests shall be carried out as per the mutual agreement between the manufacturer and the purchaser. a) Test for vibration severity of motor; b) Test for noise levels of motor; c) Test for degree of protection by enclosure; d) Temperature rise test at limiting values of voltage and...
