Working of Transformers: Explained.

            Transformers are used to step electric voltage up or down before it makes its way to its final destination. Why does this need to happen? Original power distribution voltage can range from 7,200 to 24900 volts depending on your electric utility, providers practice and the distance to the furthest member and the amount of load served. That's much too high voltage for safe home or business use.

Transmission lines connect the power to substations brimming with transformers and control equipment. This is the first place where they transform the voltage to saver be more manageable levels or the distribution system. The voltage then travels through distribution lines. It takes one or two more steps down and arrives at your home, power beats into your home's electrical outputs and lights at 120 volts while water heaters ranges and HVAC systems receive 240 volts. Both considerably are lower than the original voltage.

Transformers are everywhere in our daily lives, not just on your utility provider's lines take your cell phone charger. For example, many of these small cousins of utility transformers perform a similar function. Charging your cell phone with 120 volts will fry it instantly. So the charger converts the voltage to a more tolerable 5 volts or so the use of electricity touches nearly every aspect of our modern lives and we have transformers to thank for bringing it safely into our homes.

Transformers:

 

Transformers are composed of an iron core ring wrapped in coils. One coil is connected to an AC input voltage and is called the primary coil the other coil is connected to an output circuit with a load resistance and is called the secondary coil. The two coils are well insulated from each other and do not form a physical electrical connection. This gives a transformer its unique electricity altering properties. Transformers can either step up or step down a voltage in a step-down transformer the number of turns in the primary coil is greater than the number of turns in the secondary coil in a step-up transformer. The number of turns in the secondary coil is greater than the number of turns in the primary coil. The constantly changing current driven by an alternating voltage source induces a changing magnetic field in the core of the transformer. The magnetic field created by the alternating current in the primary coil generates the flux in the transformer core. The secondary coil converts the flux back into the current flow and produces a voltage at the load or resistance in the secondary circuit. If there are fewer coil turns on the secondary than on the primary, this is called a step-down transformer the resulting voltage in the secondary circuit will be less than the primary. In this example, we have 20 turns on the primary coil and 10 turns on the secondary coil to determine the decrease in voltage occurring in this step-down transformer we can use a simple ratio formula. This formula simply states that the secondary voltage to primary voltage ratio is the same as the secondary coil to primary coil turn ratio rearranging the formula and then dividing 10 turns by 20 turns we get 0.5 multiplied by 120 V this results in a calculated step-down voltage of 60 volts.

Hope that this will increase your knowledge.
