55. Why we do 2 types of earthing on transformer (ie:)body earthing & neutral earthing , what is function. i am going to install a oo kva transformer & 380 kva DG set what should the earthing value?
The two types of earthing are Familiar as Equipment earthing and system earthing. In Equipment earthing:
body ( non conducting part)of the equipment shouldd be earthed to safegaurd the human Earthing : In this neutral of the supply source ( Transformer or Generator) should be grounded. With this,in case of unbalanced loading neutral will not be that unbalanced voltages will not arise. We can protect the equipment also. With size of the equipment( transformer or alternator)and selection of relying system earthing will be further classified into directly earthed,Impedance earthing, resistive (NGRs) earthing.
Dear Mr Admin,
You are doing an excellent job by helping out desirous candidates to face SSB. Hats off to you!!
I have few questions, please answer them.
1) I have attended AFSB, & now I have got SSB for Army. There will be definite question on change in my preference, how should I answer them? I just wanted to join Defence,but this will be very weird answer. Please suggest.
2) Is there any means by which I can know my performance In SSB interview? I mean can I ask the IO about my positive & negative aspects at the end of interview?
3) when the IO asks any questions at the end, what should I ask?
