To allow room for oil expansion and contraction. The transformer is completely filled with the oil and when it heats up under load or due to ambient temperatures, the oil has to have a place to go. In the event of colder weather or if the transformer is not under heavy load the oil cools and contracts creating a slight vacuum inside the tank. The conservator acts as a reservoir of oil that can then flow back into the tank so that no air enters it.
What else can I help you with?
What is type of the transformer which has no conservator?
The type of transformer that has no conservator is called a "sealed transformer" or "hermetically sealed transformer." This design eliminates the need for a conservator because the transformer is filled with oil and sealed to prevent moisture ingress. Sealed transformers are often used in applications where space is limited or in environments where contamination must be minimized. They typically have a fixed volume of insulating oil, which accommodates thermal expansion without the need for a separate conservator tank.
Why does transformer conservator gauge show maximum?
A transformer conservator gauge shows a maximum reading when the oil level in the conservator tank is at its highest, typically due to thermal expansion of the oil as it warms up during operation. This expansion causes the oil to rise in the gauge. Additionally, if there's been a recent oil fill or if the transformer is in a high ambient temperature environment, this could also contribute to the maximum reading. It's essential to monitor this gauge to ensure the oil level remains within safe operational limits.
What are the causes for decomposition of transformer oil and how is this detected?
A major cause of decomposition of transformer oil is minor arcing within the transformer. Decomposition results in gas which bubbles towards the top of the transformer and upward into the conservatory tank. Between the transformer and conservator tank is a Buchholz relay, in which this gas collects, causing a mercury switch inside a float to initiate an alarm in the substation. This gas can be collected through a small pipe feeding from the Buchholz relay in order to have it analysed.
What is the rules as per transformer work?
Transformer works on the principle of Electromagnetic induction.
How do a transformer work and why they are necessary?
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage.
Does hermetically sealed transformer have a conservator?
no,hermetical transformers do not have conservator.
What are the physical parts of transformer?
Physicially it has transformer tank, conservator, bucholz relay , windings, oil
What use of conservator tank in transformer?
To enable the oil in the transformer tank to expand and contract with temperature changes.
What are the functions of Breather Conservator and Ventpipe?
A conservator is an oil tank, located above the transformer, whose function is to ensure that the oil level remains above the transformer, while allowing it to expand and contract with temperature. The breather/vent pipe allows air to be displaced from the conservator when the level rises, and to draw back in when the oil level falls.
What is the Transformer Breather?
A transformer breather is an acessory of an oil filled type transformer which is attached into the oil conservator tank; this serves as the breathing point of the unit, that when the insulating oil of the transformer gets heated up, it expands and goes back to the conservator tank and subsequently pushes the dry air out of the conservator tank through the breather which is filled with silica gel, when the oil cools down, it retracts and sucks fresh air from the athmosphere through the breather and from this point, the silica gel dries up the air that goes back in to the conservator tank. for a better understanding have a look at the following pic: http://www.csanyigroup.com/wp-content/uploads/posts/transformer-oil-diagnostics/img-1.jpg

What is the purpose of breather in transformer?
To allow the transformer to "free breathe" and yet prevent any moisture from entering. The desiccant in the breather removes any moisture in the air before it enters the tank or conservator.
Why silicon gel used in transformer?
Silicone gel is used in transformers as a cooling and insulating material. It helps to dissipate heat generated during operation and provide better insulation to prevent short circuits. Additionally, silicone gel is non-toxic, non-flammable, and has good resistance to moisture, making it a reliable choice for transformer applications.
Why will or won't a transformer operate on AC?
transformer will work on ac

How do oil cooled transformers without conservator work?
Oil filled transformers without a conservator are usually distribution transformers with relatively-low kV.A ratings. The volume of oil in these transformers is comparatively low and there is no need to allow for any substantial expansion, which is the main purpose of a conservator tank.
