Answer / jayesh kakadiya

Transformer is electrical static device, which step up or step down voltage level and transfer one side to another side without change in power and frequency.

Answer / sarvendra kumar

Transformer is an electrical static device which is useful
in step-down and step-up the voltage level at the output
side as desired.(with out changing the frequency)

Answer / gopakumar m nair

transformer is a staticpiece of electical energy which cause of electrical energy transmit to one circuit to another circuit with out changing frequency

Answer / rahul singh

transformer is a stationary device, which transfers electric
power from one circuit to another without change in frequency.

Answer / karan katrodiya

TRANSFORMER:-
ITS A STATIC DEVICE
ITS A ONE TYPE OF ENERGY TRANSFERED.
PRIMARY WINDING TO SECONDARY WINDING.
PRIMARY :- INPUT
SECONDARY :- OUTPUT
TO GENERATED OUR REQUIRMENTS LOAD.

Answer / niraj kumar

transformer is a static electrical device transverse electrical current one place to another place.
trasformer is working on electromagnetic induction.
it is the device which is to stepup and stepdown voltage.

Answer / rajnish yadav

Transformer is an electric machine that,


1> transfers electrical energy from one electrical
circuit to another,

2> dose so without a change of frequency,

3> dose soby the principle of electromagnetic induction,

4>has electric circuit that are linked by a common
magnetic circuit.

Answer / a.mohamed fazil

the transformer is device that transfer electrical energy
from one circuit to another circuit.it is also used to step-
up and step-down.For instance it convert high voltage into
low voltage vice versa.

Answer / rahul sharma

This is a electrical device for step up or step down the
voltages.It has two terminals one output terminal & other
is input terminal. Depending upon the number of turns the voltage may be
stepped up or stepped down

Answer / rizwan alam

I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase), before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
