|Why HT motor is connected in Star?
|what is the difference between equipment earth and system
|We have a bank capacitor rating of 60 KVAR for a overall
load of 160 KVA and we have connected three loads of 50KVA
each. We would like to auto matically correct PF using APFC.
How do we design it?
|Why DG set rating in KVA
|what is ht breaker
|How the main bus bar rating of 400kV switchyard with one
and half breaker scheme is calculated.
|they conducted technica for 1 hour..i also managed..they
selected 5 boys and only one girl,myself got wait
listed.whether they would call or not
|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,

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.
