The wti is the winding temperature indicator.this is
because the winndings get heated continously, so when it
goes beyond the limit,it has to be indicated tats wat we go
for wti.

Answer / dinesh kumar

The WTI has temperature imaging sensors that fitted on some
points of winding. it has four trippers. two to trip the
alarm and two to ON the oil pumps for oil circulation.

Answer / krunal

WTI is Winding temperature indicator working principle of
the WTI is as same as the conservator tank busholz relay.
When the winding gets heated so as the oil filled in the
main tank gets heated. Now there is this mercury switch
bellow type whic pushes the pointer in the direction as
heat increases. which in turn cause the pointer deflection.
this is how the WTI indicator works.

Transformer is a static device which is used to transfer the
electrical energy one place to another place without any
changing in frequency.
Transformer works on the principle of mutual induction.

Its consits of two winding is known as primary and secondary.
The magnetic flux moves primary to secondary winding.

Answer / neeraj dubey

transformer have two winding primary & secondary when gives
ac supply voltage then winding produce fux and secondary
winding behaves like magnet lines whos cuts the flux and
produce emf in secondary winding. themn it work .
transformer has work depend upon no. of turns and cores
dia.
