mellenspänningsnät

Mellenspänningsnät, also known as medium voltage networks, are electrical power distribution systems that operate at voltages higher than low voltage but lower than high voltage. Typically, medium voltage levels range from 1,000 volts (1 kV) up to 36,000 volts (36 kV). These networks serve as an intermediate stage in the transmission and distribution of electricity.

The primary function of mellenspänningsnät is to efficiently transport electricity from substations, where voltage is stepped down from high voltage transmission lines, to various end-users. These end-users can include industrial facilities, large commercial buildings, and residential areas that are not directly served by high voltage lines. By using medium voltage, utilities can reduce energy losses that would occur if electricity were distributed directly at lower voltages over longer distances.

Mellenspänningsnät are characterized by their overhead lines or underground cables, transformers, switchgear, and protection devices. Transformers play a crucial role in stepping down the medium voltage to lower voltages suitable for direct use by consumers. The infrastructure is designed to be robust and reliable to ensure a stable power supply. Maintenance and upgrades are essential to prevent faults and ensure the safe and efficient operation of these vital networks. The specific voltage levels within the medium voltage range can vary depending on the country and the specific application.
