 Related Questions Latest Answer : A synchronous motor act as a synch. Condenser when the its field winding is overexcited and there is no load attached with it. The basic application of this phenomenon can be seen in the hydro power plant in peak load hours, when the grid supplies power ... Read Answers (6) | Asked by : sudhir.v Latest Answer : IN SALIENT POLE SYN. ALTERNATOR IT IS THE CHANGE IN THE RELUCTANCE WITH SPACE WHICH RESULT IN GENERATION OF BOTH RELUCTANCE POWER & ELECTROMAGNETIC ... Read Answers (3) | Asked by : Amit Sinha In a synchronous motor armature current flows due to revolving flux which in turn rotates the load,but in no load condition armature current is zero hence thr is no revolving flux then how motor rotates? pls give books referance. What is the voltage drop for 100kw motor if the length of the cable is 200m and what is the cable size. Read Answers (4) | Asked by : srinivas 1. what is the different between CGS system and MKS system? 2. When we connect the capacitor Banks in Series with the circuit 3. What is the difference between Earthing & grounding 4. how much voltage Latest Answer : When the current lead in the circuit use the capacitor in series. ... Latest Answer : Synchronous condenser is synchronous motor running in over excited condition..
When Synchronous Motor's field winding is 'Over Excited' it supplies the KVARs
back to the the supply lines. This property is similar to the
Capacitor/Condenser. Hence ... Read Answers (2) | Asked by : mehdi Dear AllI wan to know that we are using large type of cable like 300sqmm and other and our load also in much kw but we are using a small type fuse in main supply (not HT Side) how can it bear load. Latest Answer : Fuse rating and cabel selection is depend upon the load current and fuse current is always greater than the load current. Suppose your load is motor then the starting current of motor is 3 times greater than the normal current then your fuse rating ... What is meaning of "Motor Frame Size"? What is use to determine the motor H.P? Latest Answer : For the coupling (motor to any other devices) purpose the motor frame come into picture. Its very important to match the frame size, otherwise motor may damage. To calculate the motor rating, it is required to have motor voltage rating and current ... In syncronous machines, less slip is useful or more slip is useful? Why? Latest Answer : A synchronous machine is defined as a machine which rotates with the constant speedslip= Ns-Nr/Nssince in syn m/c Ns=NrS=0The significance of slip comes only in induction machines where the slip exists. ... For 63A load we can use 25/35sqmm cable. For same rating fuse conductor size is too low. How is it possible?(Its not depends on meterial, because single strand for above cable size is enough for fuse) Latest Answer : Generally Fuse is used for short circuit protection. That means it should be higher(normally 2 to 3 times of rated current depending on design) than other installation in a perticular circuit. ...
