In our country power generate at l1.5kv. At this voltage current will high and if we transmit power on this voltages line losses will increase because P=I2R. For transmission we use high voltages i.e. 500kv, 220kv, 132kv and 66kv. At these voltages current will low and power losses will also less. For this purpose we use a step up transformer which increase the voltage and decrease the current and at grid station a step down transformer convert again these voltages in 11.5kv. We can’t use these high voltages and the help of step-down transformer we convert voltage as requirement.
I. Step up transformer
Step up transformer increase the given voltage and decrease the current. Its primary winding consists on thick wire and less number of turns but in secondary side thin wire and more number of turn’s w.r.t primary side.
II. Step down transformer
Step down transformer decrease the given voltage and increase the current. Its primary winding consists on thin wire and more number of turns but in secondary side thick wire and less then the number of turn’s w.r.t primary side.
Mutual induction:
The phenomenon in which an alternating current in one coil induces an emf in another coil is called the mutual induction.
Mutual induction of two coils depends upon the following factor:
Ø Number of turns of the coils.
Ø Area of cross-section of the coils.
Ø Closeness of the coils.
Ø Nature of the core material upon which the two coils are wound.
Principle:
The transformer works on the principle of mutual induction between the two coils. A changing current in the primary winding induces an emf in the secondary winding.
Definition:
A transformer is an electrical device which is used to increase and decrease given alternating voltage with out any changing in frequency.Business these days is a very tough task and it pays to know exactly what your doing. This is especially to true when dealing with the forex market. It is indispensable that learning forex trading and all that is associated with it to best of your ability in order to succeed.

Because forex trading is done in real time and decisions are done on the spot, a trader should be emotionally equipped and prepared to handle the demands, challenges and the stress of the market. And these, one can learn in a forex trading education.
From ancient times, people have been engaged in different types of businesses. Buying, and selling of commodities, is still the backbone of any business. Businesses have not only provided bread and butter to generations but have also helped build many great nations.
Trading is also one of the very old ways of doing business. Long ago, people traded goods for other goods. Later on, goods were traded for services and services were traded for money.
Forex trading is just one of the many forms of trading business. Simply put, forex trading is the trading of different currencies in the world. Known as the largest financial market in the world, forex trading is the least regulated market which provides absolute liquidity to most investors.
In the beginning forex trading seems very easy. But in reality, it’s quite difficult. To make money in forex trading, you should be able to buy currencies at a cheaper rate and sell them later at a higher rate. If you don’t have proper knowledge about it, you will lose a whole lot of money.
