Re: transformers parts & function of each parts

winding,secondary winding and transformer core are all the main parts of the transformer. the supply voltage is connected to the primary winding, the load is connected to the secondary winding and in the transformer core only the magnetic flux path will b established.. in power transformers(used for transmit the heavy voltages to the grid) on load tap changers used.. but in

distribution transformers off circuit tap changers

there is another type of transformers called transformers in which part of the primary winding used as a secondary winding. buccholz relay s used for the transformer protection. 24 Yes

9 No


1.primary winding 2.secondary winding primary is connected to secondary is connected core is used for magneti path as well as reduce the no load current if there is no core the no load current is more than 10-15% of full load current. how it is we r giving the supply to primary wdg

it produce magnetic field this magnetic field is oppose the cause this magnetic field produce back emf. as per lenz law that is why trnsformer is taking no load current only upto 1to2% of full load

6 Yes

5 No

1) CONSERVATOR conservator is a type of tank , used to help oil filling this is situated upper portion of the power transformer . mainly these are cylindrically shapped... 2) TANK - basically this is a container used to keep windings(both) and cooling oil. 3) BUTCHHOLZ RELAY this is a protecting device used to protect our transformer windings . this is a double ended device one end is conneced to conservator other is connected to tank. there are two windings inside the relay one for detecting oil level goin to empty and other is connected to a alarm circuit for warning 4) BREATHER - Breather is a device used for absorb the moisture content of a

oil and sucked air 5) SILICA JEL - it is a chemichal matarial these are the only one main component inside the breather basically silica jel is a brown coloured one after the absorbtion silica jel become pink 6) OIL LEVEL SCALE this is a ordinary part situated on the side of the conservator for proper oil checking oil tank wants a specific amout of oil 7) PRIMARY WINDING in the case of power transmission primary windings are the main element external connection from the power is connected to thi 8) SECONDARY WINDING this is a another windin for redusing power(in the case of step down 9) DRAIN VALVE - this valve is used for taking damaged oil from the oil tank for the proper oil collection this valve is situated under

the oil tank 10) PORCELIN BUSH This is a outer unit , this is used to prevent unwanted leackage of electricity 11) RADIATOR - This device is used to cooling oil 8 Yes

1 No


i think that answer is

2 Yes

1 No


Transformer main 1)BUCHHOLZ RELAY: it is avery sensitive gas and operated instrument which safely detect the formation of gas or sudden prssure inside the oil transformer. 2)CONSERVATOR: it is used to provide adequate space for the expansion of oil when transformer is loaded or when ambient temprature changes. 3)SILICA GEL BREATHER:

it sucks the moisture from the air which is taken by transformer so that dry air is taken by transformer. 4)DOUBLE DIAPHRAGM EXPLOSION VENT: it is used to discharge excess presure in the atmospher when excess pressure is developed inside the transformer during 5)OIL LEVEL INDICATOR: it is used to show the oil level in the transformer. 6)winding temprature indicator: used to show temprature of transformer winding. 7)RADIATORS: these are used for cooling of the transformer

5 Yes

1 No
