A 120V, 60Hz air conditioner is to be operated in a remote area where the voltage drop in the long transmission line results in a utilization voltage of 102V. Determine (a) the required step up voltage ratio for satisfactory performance; (b) the voltage ratio of a standard buck-boost transformer that most closely meets the requirements of the load with the buck-boost transformer installed. (d) Sketch the appropriate connection diagram, and show the NEMA standard terminal markings.
To the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 26.0m/s .If nothing is done to correct its orbit
Given the following next state and output equations for a synchronous sequential circuit:a. Construct the transition table (state table) for the circuit showing present states, next states and outputs. b. Draw a state graph for the circuit.
A 440-V three-hase Y-connected synchronous motor has a synchronous reactance of 1.5 ohms per phase. The field current has been adjusted so that the torque angle is 28 degrees when the supplied power to the motor is 90kW.
