No.7 correct answer please
(line), calculate the motor current and its power factor. [Hint. See solved Ex. 38.17 ] (Electrotechnics, M.S. Univ. April 1979) 7. A 3-phase synchronous motor connected to 6,600-V mains has a star-connected armature with an impedance of (2.5+j15) ohm per phase. The excitation of machine gives 7000 V. The iron, friction and excitation losses are 12 kW. Find the maximum output of the motor. [153.68 kW]
