ACverkkojännitteestä

ACverkkojännitteestä, or AC network voltage, refers to the alternating current (AC) voltage levels used in electrical power transmission and distribution networks. AC is the standard form of electrical power used in homes, businesses, and industries worldwide. The voltage levels are categorized into different classes based on their intended use and the distance they need to travel.

Low voltage (LV) networks typically operate at 230 volts (V) or 400 V, three-phase, and are used for powering individual homes, small businesses, and local distribution. Medium voltage (MV) networks operate at 10 kV to 35 kV, three-phase, and are used for distributing power to larger areas, such as neighborhoods, commercial districts, and industrial zones. High voltage (HV) networks operate at 66 kV to 132 kV, three-phase, and are used for long-distance power transmission, connecting power plants to substations and major distribution centers.

Extra high voltage (EHV) networks operate at 220 kV to 500 kV, three-phase, and are used for transmitting power over very long distances, such as between regions or countries. Ultra high voltage (UHV) networks operate at 750 kV and above, three-phase, and are used for transmitting power over the longest distances, such as between major power generation and consumption centers.

The choice of voltage level depends on factors such as the distance power needs to travel, the amount of power to be transmitted, and the efficiency of the transmission system. Higher voltage levels allow for more efficient power transmission over longer distances, while lower voltage levels are more suitable for local distribution and end-user applications.
