The Source internal resitanse Rs , When equal to Load resistance RL, the maximum transfered is of _____ % of input power?
What happens if the capacitive reactance of a transmission line is very high?
why transmition and distribution and genaration of voltage in multible of 11 means 220v,440v,11kv,22kv,,,...so on
is it possible to give the total load from the supply generator's maximum in practical?
When the load on the system is zero and Capacitor bank is on condition, is capacitor bank takes any load?

3 ph motor connected in star delta starter. when we start the motor it run in star but when in is going in delta it trips the main incoming supply. why?
1.Can anybody explain Why starters are not used for motor starting in industries? 2.
Based on CPI/CGPA they shortlist the candidates & than directly start Interview so there is no Written Exam or GD Only PI.Interview held @ MNNIT , ALLAHABAD On-Campus on 6th,Aug, 2007 & the Questions asked to me by Interview Board ( 4 People) are from HR/SummerTraining/BTP/Subject-core, POWER SYSTEM & MACHINE. time duration of I/V is about 15-20 Minutes. 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.
depending on what we can choose the rate of mccb considering that we know the total load
