Product Description

In electrical power supply, most medium-voltage systems are operated between 10 kV and 40 kV. Due to the historical development of technology and the local facts, the ratings differ a lot from country to country. The supply radius of a medium-voltage system is about 5 to 10 km long at 10 kV operating voltage, and about up to 20 km at 20 kV. Large networks or such with a high power density are therefore often operated above 30 kV.
In industrial plants with medium-voltage systems, there are still other voltages fulfilling the needs of consumers; in most cases, the operating voltages of the motors installed are decisive. Operating voltages between 3 kV and 15 kV are very frequently found in industrial systems.
Generators in power plants also generate power at mediumvoltage level up to a maximum of 24 kV. This refers both to large generators in base load power plants and to generators with lower ratings from distributed plants. Renewable energy sources mostly generate at low-voltage level.
In case of larger plants (e.g., wind or solar farms) the power is transformed to medium voltage and fed into the distribution system.
Medium-voltage equipment is therefore available in power plants (in generators and station supply systems), in transformer substations of the primary distribution level – which receive power from the high-voltage system and transform it down to the medium-voltage level – as well as in secondary, transformer or transfer substations (secondary distribution level), where the power is transformed down from medium to low voltage and distributed to the end consumer.
Apart from that, there are other applications, for example in the distribution systems of large industrial plants, on ships, in the mining industry, for traction power supply, and on locomotives or multiple units. In traction application, the predominant ratings for alternating systems are AC 15 kV, 16.7 Hz (Germany, Austria, Switzerland) as well as 25 kV, 50 Hz. For DC railway systems, the voltages are up to 3 kV as a maximum.
