How does conservator work in transformer?
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 type of transformer used in bed lamps?
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
What type of transformer is found outside a residential house?
Stepdown Transformer.
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 type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
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 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 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 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.
Which type of transformer is use in gss?
Frgi transformer
What type of transformer used in bed lamps?
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
How many wires are input in a berry-type transformer?
1 wire is input in this type of transformer.
What is the hermetically sealed transformer?
Hermatically sealed transformer is a transformer design which has no conservator. Here the dielectric insulating fluid in the transformer tank is completely sealed and is in zero contact to the atmosphere. This type of transformer is used in applications where the transformer is to be installed in harsh climatic conditions(smoke,pollution,dusty environment,etc) or user prefers low maintenance transformer. The design avoids air in the transformer tank therby avoiding sludging and oxidation of the dielectric fluid. Hence it would be safe to say that these transformers need no maintenance of the dielectric insulatating fluid(usually Oil). Normally these type of transformers are accommodated by devices that measure heat related volume variations. Gas cushion is used to compensate the volume variation due to heat. Normally the gas is nitrogen. This gas is thermally uncoupled from the dielectric liquid.
