in control panel, how can i measuring the distance between one bus bar to another bus bar. then now only for bus bar. in mpcb and contactor also. that means one mpcb to another mpcb how much distance? how can i calculate that.
A 50Hz,4-pole,3-phase,star-connected synchronous motor has a synchronous reactance of 12ohmsper phase and negligible armature resistances.the excitation is such as to give an open-circuit voltage of 13.2kilovolt.the motor is connected to 115kilovolt, 50hertz supplying. what maximum load can be the motor torque,line current and power factor?
