An electrical network is a power supply system consisting of electrical transmission lines, transformers, distribution substations, and other electrical devices designed to transmit, distribute, and transform electrical energy from the generator to the consumer. Electrical networks are used to supply electricity to residential buildings, commercial enterprises, industrial plants, and other locations.

An electrical network typically consists of several voltage levels. Electrical energy is generated at power plants using various energy sources such as coal, gas, oil, water, wind, or solar. At power plants, electrical energy is converted into high voltage and transmitted through electrical transmission lines to substations, where the voltage is converted into medium or low voltage.

After that, electrical energy is supplied to distribution substations and connected to electrical lines laid along streets and buildings. At this voltage level, electrical energy can be used to power electrical appliances and lighting.

Electrical networks are complex engineering systems that require constant technical maintenance and upgrading to ensure uninterrupted power supply. An important function of electrical networks is to ensure safety and protection against overloads, short circuits, and other emergency situations. Protective devices are installed in electrical networks to automatically disconnect the power supply in case of danger.

In addition, electrical networks require constant monitoring and control of power quality. Various devices are installed to measure voltage, current, and other parameters of the electrical network. This allows problems to be detected and resolved in a timely manner, ensuring uninterrupted and high-quality power supply.

An important part of electrical networks is automation and control systems that allow for optimal use of electrical energy and reduce costs for its production and transportation. For example…
