Overview:

Electricity is an energy source that uses electrical energy as its driving force. Discovered in the 1870s, the discovery and application of electricity sparked the second wave of industrialization. Becoming one of the three technological revolutions that have occurred in human history since the 18th century, technology has changed people's lives ever since.

The large-scale power system that emerged in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, transmission, transformation, distribution, and consumption. It converts primary energy from nature into electricity through mechanical energy devices, and then supplies the electricity to various users through transmission, transformation, and distribution.
