The transformer works by using electromagnetic induction to transfer energy from one circuit to another. This innovation made it possible to transmit electricity over long distances without experiencing much loss. It also made it easier to distribute power from a single source to multiple locations, which was a significant breakthrough for the energy sector. Today, transformers are an essential component of the electrical power distribution system, ensuring that the right voltage is maintained while electricity is transported from one place to another.

The Circuit Breaker

The circuit breaker is a vital safety feature of any electrical system. It was invented by an electric engineer, Charles Proteus Steinmetz. This device helps protect electrical circuits from overloading, electrical short circuits, and other electrical faults that could result in disaster. The circuit breaker works by opening up the circuit when it senses a surge in the current beyond a certain limit. This action helps to prevent damage to the electrical equipment and keep buildings and appliances safe from electrical fires.

In conclusion, electrical engineers have made a significant impact on our modern way of life through their inventions. The electric power distribution system, the introduction of AC electricity, the transformer, and the circuit breaker are a few of the most important inventions that have transformed the energy sector and shaped the world we live in today.
