At certain stages, the voltage of electricity is increased to enable efficient transmission over long distances with minimal losses. At other points, the voltage is decreased to safe levels suitable for homes, businesses, and industries.<br><br>\n\nHowever, their importance extends far beyond voltage conversion. Substations represent the first line of defense in the power network, protecting it against faults, failures, and outages. Equipped with advanced protection and automation systems, they can quickly isolate potential problems, preventing larger-scale damage and ensuring stability and continuity of supply.<br><br>\nAt the same time, substations enhance the overall efficiency of the system by reducing energy losses through smart energy management. They also play a central role in supporting the global energy transition, facilitating the smooth integration of renewable energy sources such as wind and solar into the grid. In this way, substations make a decisive contribution to the creation of a stable, reliable and sustainable energy infrastructure.\n<br><br>The national electricity network consists of an extensive system of specialized infrastructures designed for the safe and reliable transmission and distribution of electricity. Substations are among the key elements of this system, as they regulate voltage and distribute electricity in ways that ensure efficient and secure operation. Broadly speaking, substations fall into two main categories:\n    \u2022 those connected to the transmission network, operating at voltages of 275 kV and above, and\n    \u2022 those connected to the distribution network, which generally operate at voltages up to 132 kV.<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ec3e0cf e-grid e-con-full e-con e-child\" data-id=\"ec3e0cf\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5610cb3 elementor-icon-list--layout-traditional elementor-list-item-link-full_width elementor-widget elementor-widget-icon-list\" data-id=\"5610cb3\" data-element_type=\"widget\" data-widget_type=\"icon-list.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ul class=\"elementor-icon-list-items\">\n\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item\">\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\"><b>Beyond these broad categories, there are several types of substations, each equipped with critical components such as transformers and circuit breakers, and each with a distinct mission:<\/span>\n\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item\">\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-icon\">\n\t\t\t\t\t\t\t<svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-circle\" viewBox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M256 8C119 8 8 119 8 256s111 248 248 248 248-111 248-248S393 8 256 8z\"><\/path><\/svg>\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\"><b>Transmission substations: <\/b>These increase voltage, enabling electricity to travel long distances with minimal losses.
