1)Why electric shock is feel ?? n in a Electric Train why
we didnt feel that ?
2)What is the reason for transformer Noise ??
3)What is relation b/w Transmission Lines & Communication
Lines ?
4)Which material is used for making Transformer oil & How u
measure its dielectric strength & Name the test ?
Answer Posted / kaarthikrt&c09894209497
1.if v touch a live wire,using ur body it gets a ground so
u feel shock,in case of electric train every compartment
wheel is grounded(negative dc) so u cont get shock even if
fault occurs
2.i think its corona loss
3.trans lines used for carrying power,trans lines can also
be used as a communication line using PLCC power line
carrier communication
4.material who needs/IL335 is the indian standard oil for
tfmr oil.u can measure the dielectric strength by doing a
Break down voltage test(dielectric test for oil)
