Conservator: Transformer oil is used for the purpose of insulation and cooling. The oil should not be allowed to come in contact with atmospheric air, as it may spoil its insulating properties. To prevent this, we use conservators. The conservator consists of an airtight metal drum fixed above the level of the top of the oil tank and connected with it by a pipe.
The function of a conservator is to take up contraction and expansion of oil without allowing it to come in contact with outside air.
Breather: Whenever the transformer is loaded, the temperature of the transformer insulating oil increases. Consequently, the volume of oil is increased. As the volume of the oil is increased, the air above the oil level in conservator will come out. At low oil temperature, the volume of the oil is decreased, causes air to enter into conservator tank.
The air consists of moisture in it and this moisture can be mixed up with oil. Hence to filter the air from moisture silica gel breather is used.
Exciter: The rotor or the field coils in a generator produce the magnetic flux that is essential to the production of the electric power. The rotor is a rotating electromagnet that requires a DC electric power source to excite the magnetic field. This power comes from an exciter.
