Answer / praveen

transmission and distrubution:-
the lines which transmit power from generating station to
distrubution substaion is called transmission..

the lines which transmit power from these substation
consumers is called distrubution...

A very high voltage is transmitted to reduce losses...

The main thing we consider transmission or distrubution
is "SAG"calculation... sag of line directly propotional to
the weight of the conductor,distance between the poles etc..

Answer / balaji

T&D is a very vast feild in Electical Engg,It starts from
how power is transmitted & effectively distrubutd to user
end.Its is many areas like Loss reduction,Compensator
Design,Harmonics Compensation,Voltage Grading in Overhead
lines & Underground cable lines,HVDC(High Voltage DC
Transmission),FACT(Flexiable AC Transmission),SCADA
(Supervisory Data Control And Aquactions System)
Controlling,Protection,Montoiring,Metering(PT,CT,Optical
CT),Circuit Breaker(Vacuum Circuit Breaker,Ring Main
Unit,Isolator,Disconnector,Gas Insulated Subsataion,SF6
Breaker,Fuses),Substation Design,Pole Insulator Design
(Bushings)and latest Solid state circuit breaker, these are
major feild which seems to interesting

T&D -->Transmission and Distribution.

generation---> Transmission ---->Distribution

Answer / h.s. raveesh(9740655446)

Transmitting higher voltage using stepup transformer to
avoid loss and steping down using stepdown transformer for
distribution purpose.Transmission mission means
Transmitting higher voltages like 11kv,33kv,66kv & 110kvand
Distribution means distribution lower voltages like 230v or
440v

Answer / nilofar

it deals with how power is
generated,distributed&transmitted.it also tells about how
to save power & how we can protect our devices..

HR- Q.1 Name,hobbies & About family background ? Q2.What u know abt NTPC ?? Q3.Why u want to choose NTPC as ur Carrier's starting i.e power sector not any other Oragnisation or sector ?? Techincal Questions- Q1.What is the reason for transformer Noise ?? Q2.Which material is used for making Transformer oil & How u measure its dielectric strength & Name the test ? Q.3 Which Machine u will prefer 2 use if flammble gases are coming out at a place & why ?? Q4.What is relation b/w Transmission Lines & Communication Lines ? Q5.What is the maximum capacity Synchronus Machine & total powerGeneration in our country ? Q.6 In india Power generation is at 50Hz while in America its 60 hz ,why so ?? Advantage or disadvantage ?? Q.7 Maximum Generation Voltage in india ? Q8. What is the Voltage regulation & why its required n how much is permissible ? & causes of voltage variation ?? Q.9 Why electric shock is feel ?? n in a Electric Train why we didnt feel that ? Q.10 Have u seen/ experience of any power plant/ industry related to the power sector ? so these are the questions which not too diffcult i think was asked to me.
