Question 
What is meant by transformer, why it should be used, with 
out that equipment what happens if we transformed the 
supply?

  Re: What is meant by transformer, why it should be used, with out that equipment what happens if we transformed the supply?
Answer
# 1		 
transformer is an equipment which is used to transfer 
power, voltage, current with out changing its frequency.it 
is also used to increase or decrease the voltage by using 
diffeent types of transformers like step-up and step down 
transformers.if we transfer the power with out transformer 
the voltage rating will come down as the distance of 
transmission is increasing.

Answer
# 2		 
A transformer is used to increase or decrease the voltage 
level.The types of transformers are 
               1.step up
               2.step down
               3.centre tapped

Answer
# 3		 
TRANSFORMER IS A STATIC DEVICE WHICH TRNSFORMS THE POWER 
FROM ONE CIRCUIT TO ANOTHER CIRCUIT BY CHANGING THE VOLTAGE 
NOT BY CHANGING THE POWER AND FREQUENCY.
TRANSFORMERS ARE USED TO TO GET THE DESIRED VOLTAGE LEVEL.
IT IS NOT POSSIBLE TO TRANSFER THE POWER WITHOUT 
TRANSFORMER.BECAUSE ELECTRICITY CAN'T BE SENT AT 440/415V 
FROM GENERATING STATION TO CONSUMER'S PREMISES.WE SHOULD 
TRANSMIT AT HIGH VOLTAGE(IN KV).OTHERWISE POWER CAN'T BE 
RECEIVED.

Answer
# 4		 
Transformer is that stactic device which transfers power 
from one ckt. to other w/o changing frequency.

Transformer is used for stepping up & down the voltage 
levels or as per requirments whenever needed. 

Voltage level should be lower for Consumers like 
Industries, Domestic, etc as compared to Generating 
stations, Substations, switchyards hence w/o Trafo, voltage 
level can't be changed like stepping up or down, hence to 
get desired voltage level, we have to use transformers.

Answer
# 5		 
Transformer is an static electrical device.which transfor 
energy from one electrical circuit to another 
circuit,without changing in frequency.if we transformed 
without using this device the cost and looses becomes more

  Re: What is meant by transformer, why it should be used, with out that equipment what happens if we transformed the supply?
Answer
# 6		 
A transformer can accept energy at one voltage and deliver 
it at another voltage. This permits electrical energy to be 
generated at relatively low voltages and transmitted at 
high voltages and low currents, thus reducing line losses 
and voltage drop hence transformers are issential for power 
transmition

Answer
# 7		 
transformers are static device....they are used to step up
or step down the voltage in the transmission line....without
transformers the transmission will not be possible because
from the generating station the the voltage must be stepped
up for transmission purpose and after that it has to be
stepped down for domestic and industrial usage
