In one village i have seen Earthing transformer's earthing
line was also connected to the Transformer body to ground
the transformer,can it be possible to maintain 0Volt
reutral line this way?
Answer Posted / ansarelectrapower
distribution transformers are mainly used
delta/star .HTside is delta
LTside is star because star point is earthed.mainly two
conductors are connected through the transformer
neutral .that is body earth and one conductor coming
directly from earth pit.

Define characteristics impedance?
if in 3-phase system voltage=440V,frequency=60Hz, current=400A. then if it is single phase then current=? and if it is single phasing then current=?
Actually I have a doubt on neutral and earth.we use Ac power without taking neutral by connecting to earth,but at that time does it affects on efficiency of any electrical components or no? If yes how?

Dear All, I am new in construction company , my boss ask a question at time of interview , If we have 60MW generation and Single Power Transformer step-up we have. if CMR 50/60MVA , ONAN, ONAF respectively , is it sufficient or not ? for that much power to transfer,
A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?
