place to another place with out changing the frequency

Answer / parmod kumar

It is a static device which is working on the principle of
electrocmagnetic induction and transfer voltage from one
level to another level without change in frequency i.e
frequency remain same in primary as well as secondary.

Answer / ashokchakri

it is a m/c which is used to transferred the power from one
place to another place with out changing the frequency

Answer / nid

transformer is a static machine that can change the voltage from one level to another level without any change in power and frequency
ie when vtg reduces in secondary the current increases so as to keep the power in same value
V1I1 =V2I2

IN CASE OF POWER TRANSFORMERS THE SECONDARY CURRENT CAN BE EASILY FOUND OUT BY JUST DIVIDING THE kVA RATING BY .75

As we know multiplicity factor derivation equation is as below MF = main c t ratio / main p t ratio * meter c t ratio / meter p t ratio * meter dial constant Where in digital meters for HT kwh import export now a days meter constant are calibrated already which is 1 So my question is For HT 11kv 110 v line values are as below Main c t and p t ratio are 11000 v and 110 v and 20/5 means 20 amp and 5 amp Now meter values are 11000/√3/110√3 and primary and secondary amp are displayed as -/5 amp on kwh meter so what will be the MF for this meter ?
