jõuülekandesüsteemi

Jõuülekandesüsteem, or power transmission system, refers to the interconnected network responsible for generating, transmitting, and distributing electrical energy. It begins with power plants where various primary energy sources like fossil fuels, nuclear reactions, or renewable resources are converted into electrical energy. This generated electricity is then stepped up to very high voltages using transformers to minimize energy loss during transmission over long distances.

The high-voltage electricity travels through transmission lines, a network of conductors supported by pylons. These lines form the backbone of the power grid, connecting power generation facilities to substations closer to consumers. At substations, transformers reduce the voltage to lower levels suitable for distribution.

The distribution system then carries the electricity through a network of lower-voltage lines, often seen on utility poles in urban and rural areas. Finally, at the point of use, such as homes and businesses, further voltage reduction occurs via local transformers, delivering electricity at the required voltage for appliances and equipment. The entire system is carefully managed and monitored to ensure a stable and reliable supply of electricity, balancing demand with generation. This complex infrastructure is crucial for modern society's functioning, powering everything from lighting and heating to industrial processes and digital communication.
