The Principle Parts of a Transformer and their functions
are:
# The Core which makes a path for the magnetic flux.
# The Primary coil,which receives energy from the ac source.
# The Secondary coil,which receives energy from the
primary winding and delivers it to the load.
# The enclosure,which protects the transformer from
dirt,moisture,and mechanical demage.
# Purpose of Oil Conservator:
1.To protect the warm oil against contact with the oxygen
in the atmosphere and thus prevent deterioration of the oil.
2.To contain the changes in oil volume which occur during
thermal cycling.
3.To prevent the entry of air and hence also the
condensation of water on the inside of the transformer tank.
