Answer / baljinder singh
transformer transfer electrical energy from circuit to
another without changing its supply frequency.so it is rated
in KVA and not in Kw.

Answer / sirisha
transformer is a static device which is used to transform
the energy from one circuit to another circite witout
change in freequency.there is no moving parts so lossess
are less when compared to any machine.transformer rating
measured in kva only
if u ak any qn i will answer u

Trans, working just &just on mUtual indiction fundamental.
for step up and step down. not a another.

The fundamentals of transformer is the transfer the energy
from one circuit to other circuit due to magnetic induction
between them without changing the frequency. Here no
movable parts. So losses are highly reduced.
Magnetic Induction (M) = L.dt/dI.

I have connected 04nos. earthings to a transformer through 04nos. earthing pits seperately. 02nos. earthings are connected to T/F body, and 02nos. earthings are connected to T/F neutral.T/F capacity is 2000KVA, 11KV/415V. But after completing of 02 years successful operation ,we are facing following problems- 1. CT/PT occured blast one time 2. HT cable box occured blast two times 3. One body earthing strip and one neutral earthing strip of transformer are overlapping at some places. Whenever these two strips are pressed at overlapped points, they made spark. What is the reason of spark? Please explain the reason & rectification of above problems
