mellomspenningsnett

Mellomspenningsnett refers to the electrical distribution network that operates at medium voltage levels, typically ranging from 1,000 volts (1 kV) up to 36,000 volts (36 kV). These networks are a crucial link between high-voltage transmission lines and low-voltage networks that supply electricity to individual consumers. The primary function of a mellomspenningsnett is to efficiently transport electricity from substations, where the voltage has been reduced from transmission levels, to local distribution points.

These networks are characterized by their overhead lines, underground cables, or a combination of both. They serve various customers, including industrial facilities, large commercial buildings, and smaller communities that require a higher power supply than a typical residential area can handle. Substations play a vital role within the mellomspenningsnett, containing transformers that step down the voltage further before it enters the low-voltage network or step it up to transmission levels. Protection devices such as circuit breakers and fuses are installed throughout the network to safeguard against faults and overloads, ensuring the stability and reliability of the power supply. The design and maintenance of these networks are complex, involving considerations for load capacity, fault current levels, and environmental factors to deliver electricity safely and effectively.
