Question { OPTCL, 136166 }

what is name of transformer oil ?

Answer

Transformer oil, or insulating oil, is usually a highly-
refined mineral oil that is stable at high temperatures and
has excellent electrical insulating properties.

It is used in oil-filled transformers, some types of high
voltage capacitors, fluorescent lamp ballasts, and some
types of high voltage switches and circuit breakers. Its
functions are to insulate, suppress corona and arcing, and
to serve as a coolant.

Question { L&T, 13236 }

will we get shock from dc?

Answer

dc voltage is more dangerous than ac. dc voltage must be
greater than 110v.

Question { 8474 }

what happen when transformer connect on dc supply.

Answer

voltage induced in a coil depends upon the rate of change
of flux linking it, according to Faraday's law. dc voltage
produces constant flux which does not change with time. so
no voltage can be induced in the secondary winding.
