which motor is used in electric train...???????

Answer Posted / jeykishan kumar.k

its an obvious answer: DC SERIES MOTOR

reason:- In trains there are many comartments full of
passengers,so during the starting it requires high starting
torque and in dc series motor torque T proportional to Ia
square and Ia=If,so if the motor started without any load
then the armature current will be very high which may
damage the motor.

As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
