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.
