what are the types used for alternator earthing,what will happen if more than two alternator is working in parallel with each having own system earthing.is there any possibility for circulating current in between two system.
BEL,
3 6566Why we should use delta connection in primary and star connection in an distribution transformer, which converts 400v a.c. voltage to 33kv.
15 35301What is the difference between CRNO and CRGO in an transformer and what is the advantages of these two.

In the N-series schneider reclosers. What is the difference between current during fault time and current at tripping? This appears in the Event log in an event of a trip out.
Can we test the alignment of End shield and stator of turbogenerator without rotor insertion? Also how to fix maintain the alignment at site installation?
advantage and disadvantage of team work?
from where the self excitrd induction generator get the power?why is the voltage regulation is poor of seig?
Between educational qualification and practical work experience, give us a brief explanation on your practical experience in your past Endeavour that you performed well to the satisfaction of your past or present employer?
we have require a Motor (1500kW, 6.6kV, 50Hz) which shall operate at 1500rpm during 30min and after it shall run on 500rpm during 15min. The same cycle shall be repetitive during the whole working days. Which method is best and economic to achieve such type of task. VFD, VVFD, Pole changing motor etc.
While performing stability test of differintial cts how to know the voltage and current on both side of the transformer?
Is it possible to convert Dependent sources to its equivelent current or voltage Sources ?????
what r PID controllers?why they r used?what is there purpose?plz Explain in detail
Advantage of LT panel vs HT panel
I WANT TO know WHICH WAY IS BETTER FOR CONNECTION BETWEEN POWER TRANSFORMER AND MAIN DISTRIBUTION PANEL. 1-IS BETTER WE USE CABLE? 2-IS BETTER WE USE BUS DUCT? my transformer rate power is 2500KVA
Why does an induction generator is preffered as compared to synchronous generator in especially a wind energy power production project?
some time we open engine breaker 8.0 MW load but plant not trip. and another time engine open 4.0 MW load engine trip why? individually engine breaker open & individually emergency stop why difference?
Is it true that in the 3 phase transformer, the limbs of the core are at 45 dgrees to each other. if true, why?
how to calculate the breaking capacity of different breakers.
