Explanation on Electronic Transformers
Electrical transformers are vital to the electrical grid. Without electrical transformers the power grid would be all but inoperable. As the electrical current travels away from its source, it becomes degraded and unstable. In other words, electrical transformers serve the vital task of regulating the flow and voltage of electricity as it travels along the power grid.
The Importance of Electrical Transformers
As electricity travels away from the power plant, it rapidly degrades. This degradation results in a weakened electrical current and fluctuations within the power system. If the electricity that is going into a home is fluctuating, then it will damage the sensitive components in electrical items in the home. Also, if the current had weakened substantially, then it will be unable to properly power the items in the home. Electrical transformers provide the vital task of regulating and boosting the voltage of the electrical current. In other words, transformers act as a signal booster for the power lines. Just as a signal booster for a wireless adapter can dramatically increase the range of the device, a transformer can dramatically increase the range that power stations can send their electricity.
How a Transformer Works
The key to a transformer's ability to regulate the flow of electricity stems from electromagnetic induction. Electromagnetic induction is the result of an electrical current being exposed to a magnetic field. This exposure can be used to either increase or decrease the voltage in the electrical current. For increasing voltage, it is important for the magnetic field to be oscillating. An oscillating magnetic field will increase the voltage of an electrical current that is exposed to this field. As electricity enters the transformer, it is exposed to a series of magnetic fields that are oscillating at a high rate. This oscillation allows the electrical current to receive a boost in voltage that keeps the current stable, and allows it to safely power electrical items.
